2 Unfriendly Bala Sharks - Cramped Quarters 8/25/12
Hello,
<Hello Rheanne, Rick here.>
I have two Bala sharks, one is roughly 25cm and the other is
about 11cm.
<Still small. Can get as large as 40 cm. Also said to prefer to be in
groups of five or more.>
My tank is 180litres and stocked with Mollies, Swordtails,
Platys, Gouramis and Chinese Algae eaters.
<Too small for Bala sharks. An 8-foot tank (240 cm) is
recommended, but bigger than yours in any case.>
When I purchased the Sharks I had no clue they could get so huge.
<One of those fishes where the adult size is buried in the fine print.
Research before buying, even if you have to use a book on the rack at
the store.>
I've had some in the past and they did not get anywhere close to 25cm.
<Different species maybe?>
Anyway, my problem is that as soon as I turn the lights off my two
Sharks begin acting extremely shark like, attempting to eat any fish in
their sight.
<Trying to make space?>
They succeeded many a time, of course providing the fish is small (the
size of a neon terra) enough to fit in their mouths whole. All my
Mollies, Swordtails and Platys seem petrified at night, they all stay at
the top away from the Sharks.
<Everybody is stressed. Bala sharks are in a constricted space, everyone
else is terrified. Not sustainable.>
I feed my fish twice a day, my Sharks eat the algae wafers I drop in for
the Chinese Algae eaters. So my theory is that the Sharks really
shouldn't be hungry, surely if they were they would behave the same at
day time.
Which they don't! Their so peaceful in the day.
<Probably not hunger-motivated behavior.>
What I am wondering is if it is possible to transfer these two Sharks to
a 90litre tank? I have a feeling this is too small but I thought it
worth asking anyway.
<Larger, not smaller.>
My other option if that can't work is to sadly give them to the Pet
Shop, which needless to say I don't want to do. I love my Sharks, but
their behaviour towards the other fish at night is too stressful for the
other fish (well from my observations).
<A larger tank is best.>
Oh and just to note both Sharks are still growing!
<The problem will only get worse.>
Thanks in advance for your time and advice.
Rheanne
<Good luck. - Rick>
Re 2 Unfriendly Bala Sharks - Cramped Quarters 8/25/12
Hello Rick,
<Rheanne>
Thank you very much Rick for your help.
<Sure thing.>
In future I will definitely look into the fish I buy in greater depth.
<Good habit to form>
Just one more question if it is that their looking for space, why do
they behave that way only at night? They look like they are hunting for
food.
They follow fish around and peck after them. They both sleep in
nice open areas in the tank, so I thought they had space, I have a
better understanding now, thanks. I'm just curious as to why they behave
different with the light off.
<Animal behavior is the stuff on which entire careers are built. Maybe
in daytime they are intimidated by a bigger fish (you). They are
still growing, so maybe food is still part of it even though they are
well fed in daytime. Hard to say. Sometimes you have uncharacteristic
behavior from one individual and others can learn that behavior. That's
part of what makes keeping fish interesting. Regardless of the
reason, the problem will get worse as the balas grow.>
Also, roughly how many litres is in a 280cm tank?
<Very large, ~200 gallons/750 liters. Should you choose to go that
route, be sure to understand what you are getting into.
Personally, I think there are more interesting choices than Bala sharks
to populate a tank that size.>
Thanks again.
<Welcome. - Rick>
Minnow
Sharks, sys... 8/31/11
Hello Hello,
I just got two Bala sharks and two rainbow sharks for my dorm tank all
of which are around 2 inches right now.
<For now; healthy specimens should add an inch every month or
two.>
It is 15 gallons (more long than high) and I figure it will hold me
till spring when I plan to get something at least 55 gallons
(preferably bigger).
<55 gallons is adequate for a single Rainbow Shark; two specimens
can, will fight in such an aquarium, and won't really be at peace
in anything less than 100 gallons. As for the Bala Sharks, these
SCHOOLING fish get extremely large, 10-12 inches, within a couple
years, and even a minimal group of three specimens would need well
above 75, 100 gallons.>
In the mean time...I keep trying to find info online as to what kind of
set up my tank should be to keep these fish happy, but just can't
seem to find it. So if you have any suggestions, please let me
know.
<Do read:
http://www.wetwebmedia.com/fwsubwebindex/bala_sharks.htm
http://www.wetwebmedia.com/fwsubwebindex/redfinsharks.htm
And also read here; sensible stocking options would be for a 10 gallon
tank, but with a bit more space so perhaps slightly more (but the same
sorts of) fish.>

Moving
Bala Sharks: Need Advice - 8/17/10
To Whom It May Concern:
I currently have an established tank with three balas in it. I love the
fish! My dilemma is that I am about to move back to school, and I need
advice on how to transport them (i.e. get them into smaller
containers).
When I moved home for the summer, I had a heck of a time catching the
three fish (took well over an hour) using a net to coral them into
separate containers.
<Mmm, two nets... of size, soft mesh... and great care so these
minnow sharks don't launch themselves out during the process...
LARGE poly fish bags... and a source of oxygen (likely a friendly fish
store)... and some sort of insulated container/s... fish box/es,
cooler/s>
My concern is that they seem to have grown over the summer and are
perhaps even more fidgety. Is there a method that ensures or at least
greatly decreases the chance of injuring these fish in catching
them?
Thank you in advance!
Peace,
Matt
<Welcome. Bob Fenner>
Should I keep my Bala Sharks? (RMF, six Balas in a 150 US
gal.?)<Mmm, yes, can work>
2/18/10
I currently have a 55 gallon that has too many fish.
<Ah! So easily happens!>
Because of this I am in the process of moving to a 150 gallon tank I
bought. I have two Bala sharks, approximately 6" in length, along
with angels, gold barb minnows, Gourami's, etc. I have read that
Bala sharks like to be with their own and need large amounts of
space.
<Bala Sharks do need space, yes, but they're perfectly happy in
community tanks. They are nervous, which is why they damage themselves
if scared by nippy or aggressive tankmates. But if they're kept
with peaceful tankmates, they're fine.>
Should I look into getting a few more to add to the two I already have
or should I just keep the two I currently have for the tank I will be
setting up (which wont be for another month or two)?
<Certainly, the more the merrier.>
I only ask because I have someone who has 4 small Bala sharks (about
3" long) who may be looking to rehome them and I wasn't sure
if it was a good idea to add a total of 6 to a 150 gallon tank.
<It would be a bit of a squeeze, to be honest. As juveniles
they'd be fine, but once above 20 cm/8 inches, six Bala Sharks will
be putting a terrific strain on the aquarium and the filter, even
without the Angels, Barbs and other things you already have. Do bear in
mind Bala Sharks can exceed 30 cm/12 inches in length, though aquarium
specimens that size are uncommon.
Adding a sump to expand water volume would be a relatively easy and
unobtrusive way to increase water volume, but you'd still have big
fish in a relatively short (left to right, front to back)
aquarium.>
Thank you for your time!

... Bala sharks... env.
1/31/2010
hi guys and gals.
<Nick... where's your grammar man?>
have a question or 2, regarding Bala sharks and a new tank setup I
would like to do.
currently, I have a 75gallon tank with 2 Bala sharks and 4 large
Tinfoils.
the Balas are about 4 inches now, just over year old. we lost 2
Tinfoils in a day, due to sudden ammonia increase.
<Insufficient biofiltration, circulation?>
got it under control, but too late for 2 fish. obviously we made an
error in sizing here and these fish grew too big for the tank. even
with 2 whisper filters, it cant cope. I love the Bala sharks and they
didn't seem to bothered by it all, but they are only going to get
bigger I know, so I'm planning on setting up a new tank. be the 5th
tank running now...
id like to make a tank, just for the Balas, maybe get a few more, end
up with 4 or 5. my questions are though. is length more important than
width and height?
<Surface area most important>
I will probably build this tank myself and I know they like to
swim.
2nd question. I have read conflicting reports on this, but seem to get
impression from your site, they dont like fast running water,
correct?
<Please read here:
http://wetwebmedia.com/FWSubWebIndex/balasysfaqs.htm
and the linked files above>
I have caught mine playing in the smaller filters flow but not sure if
they actually like some current or not. I had wanted to use real rock
as a background and gravel base, almost like a river I suppose, but
want to know if they would prefer it to flow, or be still. planned on
using similar set up to my saltwater tank, but using wet/dry filter
instead of sump/refugium.
have outflow one end and inflow the other. or be better if I rethink it
so no flow?
any suggestions on other ideal environment they like that could be
incorporated into a home aquarium. planned on just having Balas in
there, unless they like company of another species. they get on well
with Tinfoils but just too much for current tank.
any tips be great...
thanks

Fish (Potamotrygon and Balantiocheilos;
cohabiting) 1/18/10
Can Bala sharks live with rays if in correct tank size? Thanks
<In theory, yes, but unless you're running the Shedd Aquarium
it's hard to imagine you'll have a tank the correct size. I
mention this because Stingrays need huge tanks to do well, a tank twice
the disc width of the species front to back, and at least three times
its disc width from left to right. This would be about 6 feet long and
4 feet wide for the "small" species usually sold, like
Potamotrygon Motoro that get to 18-24 inches in disc width. Let's
say you start with a tank 6 feet long, 4 feet wide, and 2 feet deep,
that's 48 cubic feet, or 360 US gallons. Oh, you say to me, surely
most people keeping stingrays don't have tanks that big? Indeed
not.
And most people keeping stingrays end up with dead stingrays. Very,
VERY few people keep them alive for anything like their natural
lifespan, often losing them within the first year. Let's say a
group of three or four Bala Sharks needs another 125 gallons on top of
that (a conservative estimate, given their adult size and need for
company of their own kind). We're then looking at a tank nearer 500
gallons. To be sure, you could get by with less volume if the
filtration was extremely robust and you did massive water changes, but
given the cost in RO water to reduce nitrate levels, plus the minerals
you'd need to harden the RO to the appropriate water chemistry,
it's still very expensive. So, think VERY carefully before
embarking on a project like this. If you haven't already bought
Richard Ross' excellent (and very cheap) book "Freshwater
Stingrays", do so NOW; it's the best $9 you'll ever spend.
If you can't afford that book, you can't afford to keep a
stingray. Cheers, Neale.>
Pictus Catfish disappearance 3/26/09
Hello,
<Hello Michelle,>
I have had a ten gallon aquarium with a small pictus catfish and a
small Bala shark for about a month now.
<Completely unacceptable for these fish, and any/all problems you
have will come down to this. Both these fish are schooling species for
a start, so need to be kept in groups. I'd recommend at least three
of each, and ideally 5-6 of each, if you had the space. Pimelodus
pictus gets to about 12 cm in length under aquarium conditions, so it
isn't too big, but Balantiocheilos melanopterus is much bigger,
easily 25+ cm. In other words, you'll need a 115 l/30 gallon tank
for the Pimelodus, and a tank at least twice that size for the
Balantiocheilos.>
They got along perfectly fine.
<Famous last words.>
I kept them on a diet of sinking shrimp pellets, flake food, and frozen
brine and neither had trouble eating. I noticed both yesterday when I
fed them, but today the pictus catfish is gone. I don't believe
that the Bala shark attacked/killed/ate the pictus catfish overnight,
especially when I've kept them comfortably fed.
<Likely jumped out, or simply died and the corpse was eaten.>
I've read that the pictus catfish doesn't jump, burrow, or
hide, and to check I've searched all around the outside of the
aquarium, stirred up the gravel, and pulled up the fake plants, but it
is nowhere to be found.
<Perhaps it chose suicide over a long, lingering death? I don't
mean to be harsh (though I admit that I am) but there is absolutely no
way either of these fish could be maintained for long in this tank.
They were going to die quickly one way or another.>
Also, it had a habit of circling up and down the wall by the filter,
but I checked the filter (a long shot) and it wasn't there
either.
<Any cats or dogs? Fish-flavored jerky would be gone in no
time...>
Any theories?
<Several.>
Thank you for your time, Michelle
<Please do review the needs of your fish PRIOR to purchase. It's
best for all concerned. Do see my article on stocking small tanks,
here:
http://www.wetwebmedia.com/ca/volume_5/volume_5_3/stocking.htm
Return the Bala Shark and select a few small fish viable for the tank
you have. Cheers, Neale.>
Re: Pictus Catfish disappearance 03/26/09
Oh. Um, I don't know how it's possible, but I just found the
catfish back in the tank, against all reason. Thank you for the advice;
as much as I love them both, I'll return them both and get more
suitable fish from your article. Lesson learned, I will never listen to
the fish care/tank size labels at Petsmart again.
Sincerely, Michelle
<Hello Michelle. Well, today you've been [a] lucky and [b] wise,
which isn't a bad way to be. I'm glad you've found the lost
fish, and I'm even gladder you've returned them and are now all
set to stock with some sensible fish. May I humbly suggest that no
matter what you add, add some Cherry shrimps. These are about the most
fun you can have with 10 gallons of water! They're colorful, easy
to keep, active, and best of all, breed readily. Watching the newly
hatched babies is quite the most darling thing! Cheers, Neale.>
Stressed Bala sharks... In a 5 gallon system? And
more nonsense, no reading 03/19/2008 Hi, I have a 20l
tank. <!? A twenty long, or twenty litres? A five gallon tank?

Recently i bought new fish, mollies. After introducing them i
also upped the water temperature it was about 70 and i increased
it to 74. This caused ich, <Mmm, no> both of my sharks
showed signs of stress, constant swimming up and down the glass.
I treated the ich with Maracide but both of the sharks stopped
eating and soon died. <... you haven't read on WWM...>
After treatment for the ich i did a full water test. Temp 74, ph.
7.2, ammonia 0, nitrite 0, nitrate 40ppm. <Too high> All of
these are good according to my test kit. <... incorrect> I
reintroduced 2 new Bala sharks <Stop!> and used 20 ml of
stress coat. <What!?> It has been 24h since then and both
sharks are doing the same thing, up and down the glass and i fear
losing them the same way as the others. The other occupants in
the tank are 6 mollies, and 4 red eye tetras. Please help me
figure out what is wrong and how i can de-stress the sharks.

Bala Shark hlth., sub terminal
mouths 11/25/2007 Hi Bob- I was doing some web search
and came across several advices from you on Bala Shark. My son has 20
gal tank with 4 Barbs and 2 Bala Shark for over a year. One of the Bala
died about 5 months ago and we have not replaced it yet. The current
Bala is about 1.5 in big. In the last 3 weeks or so, Bala Shark's
mouth has developed a down ward spout like feature. First I thought
that something must be stuck in the mouth but apparently fish is doing
fine over 3 weeks and there seems to be no adverse effect on the fish.
Have you seen this before or do you know what causes this? Should I be
concerned about this or just enjoyed this "downward spout"
view? Thanks for your advice. Regards, Jay <Greetings. Bala/Silver
Sharks, Balantiocheilos melanopterus, do have somewhat turned-down, or
at least under-slung, mouths anyway. So without seeing a photo of your
fish I can't say whether this is within the range of normality or
something unusual. Physical damage, such as fighting or jumping, can
cause fish to dislocate their jaws, and it is possible that this is
what has happened. If it is, there's nothing really that you can
do. Re-articulating fish jaws is possible, but something for a vet, not
a hobbyist, to do because of the fragility of the skeleton. On the
other hand, provided the fish is feeding properly, I wouldn't worry
about it too much. Do bear in mind that you cannot possibly keep a Bala
Shark in a 20 gallon tank for much longer. Wild specimens reach 35 cm,
and even in aquarium lengths of 20-25 cm are perfectly normal. The
minimum aquarium for these fish would be 150 cm in length. Kept in
tanks that are too small these fish become nervous and sooner or later
jump out the tank. Cheers, Neale.>
Balas and pictus and sun cats in a 29 10/17/2006 Please I
don't know what to do with this shark! I purchased 2 balas today
and added them to my existing 29 gallon tank. <<Without
quarantine to a 29 gallon tank? These fish get to 14 inches in length
and school. 10x your tank size or return to the LFS.>>
When I went to watch them this evening I noticed one of the balas has
completely lost an eye and don't know to move him/her, leave him,
or god forbid put him out of his misery. <<This fish is doomed in
your tank either way.>> He seems to be twitching a little and
staying relatively in one spot the other fish are so far leaving him
alone however I don't know how long that will last as he is in with
some African cichlids and 2 pictus cats/1 sun cat. <<Your tank is
unbelievably improperly stocked. Your pictus get to 4 inches
plus each, and the Sun catfish to 18 inches. Add that to the
2 balas, and Im sure you understand how utterly ridiculous this
is. Im sure your fish store told you they were fine, but
theyre not. Please research before you buy animals.>> Should I
move him or leave him, and will this cause infection with other fish??
<<Either return the catfish (all of them) and the balas, or
acquire a tank of hundreds of gallons.>> Thanks for your
help - -TJ <<Glad to help. Lisa.>>
Balas in a 30 - Soon to be Silver Shark
Sardines? Hi I have 3 Bala sharks that are at 2.5 inches...
<Will get *much* larger. Say, 14 inches? I do hope that you have
adequate housing for these fishes.> ...now with 4 neon tetras I was
asking how many other fish could I get. <Well, that is a very
subjective question. It depends on the size tank, what species you want
more of, etc. For example, I could say that you could get 2 more fish,
and you could get 2 glowlight tetras or two Oscars.> And if you have
any suggestions of the fish I should get. <Again, depends on the
size of the tank, though most peaceful catfishes, notably of the genus
Corydoras, and small cyprinids would mix decidedly well with your
current assortment of fish.> Oh yeah I have a 30 gallon tank
<Disregard what I previously typed as to fish suggestions, look up
at my first carroted response. Your 30 gallon tank is in no way
adequate for the Bala, or Silver, Sharks you are currently keeping. You
should not be looking to get more fish, but looking to find a new, more
appropriate home for your current piscine stock, or at least the
Sharks. Do see the following article for a bit of information on Balas:
http://www.wetwebmedia.com/FWSubWebIndex/minnowshks.htm.
On a side note, please make a point to research purchases before you
make them and to stock according to the adult, not current, size of the
fish intended for purchase. If you cannot provide for an adult in your
tank, don't buy the baby, no matter how attractive they may be. (I
have long had a "thing" for Balas, but continue to refrain
from making a purchase, for fear I could not adequately provide for
them in even the largest of my aquariums). Best of luck to you, Mike

capitalization!>>
Sand and
balas Hi guys and gals, <A gal for ya today - Sabrina here> I
found your site looking for info on Balas and got sucked
in. Here it is three hours later and I'm still reading,
wonderful site! <Thank you for the kind words!> I
have two questions. 1. What is the growth rate of the Bala
is there is one? <Depends upon health, feeding, etc.>
I've had one for about a year with some silver tip cats and a pleco
in a 20g tall. He is doing fine and has grown to about 3.5
inches and I want to put him in his own tank with some other Balas. I
read they should be in groups of at least four.
<'Tis a good idea, they are definitely schooling fish.> I
want the tank to last at least three years, what size should it be
<I would aim for 75 gallons or more, if you can swing it, for a
handful of these fish> and how big can I expect him to be by
then? <In three years? Again, depends upon
several factors, but assuming all is well, I would think that he may be
fully grown by then, at or around a foot in length.> Secondly, this
may sound dumb...I love the look of sand but don't know much about
it. Would the average play sand at Home depot stay on the
bottom of the tank and not cloud the water? <I don't
know that I'd trust just any average play sand.... Talk
to a good fish store in your area and ask if they carry sand in
bulk. I know one of the sands that I used to use in Kansas
was marketed as a sandblasting sand, but was ideal for aquarium use,
strangely enough. Steer clear of aragonite sands, as that
will alter your pH.> Balas are pretty quick and I'd imagine with
the filter's currents and all sand would easily get blown
throughout the tank. <Well, depending upon how large of a grain it
is, that could be a huge issue, or none at all. In your
case, I'd probably try to find a sand that's very large.> Is
it a hassle? <It can be. It is my substrate of choice for
planted aquaria (along with some other stuff), but in an unplanted
aquarium, it will compact and create some water quality issues if
it's not well stirred occasionally. Try to find
something that suits your tastes and is a large enough grain size that
you can vacuum it easily. Wishing you
well, -Sabrina.> JayS Temporary Fish Housing
(12/23/2003) Hi-ya thanks for any help you can give me. I am
wanting to move my community tank upstairs as a larger tank has been
bought for the living room to host Discus. The tank currently running
is a 35 gallon community tank. With around 15 fish, biggest of which
are silver sharks ( a pair ) around 3-4 inch in length. <Are these
Bala "Sharks" (Balantiocheilos melanopterus) or Hemiodus?
Either of these will get bigger and need a bigger home. Depending on
the projected adult size of your 15 fish, your tank may be
overstocked.> The other tank is a 75 gallon which is not set-up as
yet. It will have a Eheim 2026 pro II for filtration. I am wanting to
move the fish into this larger tank temporarily. So I have a couple of
weeks to clean out and replace various parts of the old tank.
Just wondering how quickly I can move the fish into this new
tank without risking their health. I will start with just a couple of
the more hardy fish like the mollies and the green tiger barbs. The
tank is quite large for the fish going into it. <not really> How
long should I leave the tank before any fish go in? assuming its free
from chlorine. <Seed it with water & filter material from the
35, it will cycle very quickly and you should be able to start after
just a few days transferring a few fish every few days. And how quickly
should I add the rest? <No clear-cut formula here. Maybe 1/4 of the
fish every 3-4 days. If you can get some Bio-Spira (check
Marineland's website for info), you can cycle the tank
instantly.> I will then of course have to slowly move them back to
the original. <Consider Bio-Spira> Would greatly appreciate any
tips or hints you could give me, in this stressful time for my little
friends!! <Your "sharks" would be better off in a 55G tank
than a 35--they need the swimming room of a 48" long tank. Good
luck, Steve Allen>
Balas in a
75? I have written several times recently about setting up a
75-gallon FW community. Your advice has been invaluable. I'm at a
turning point now, I think. I started with three little Buenos Aires
Tetras and I have added three little Bala "Sharks." I've
had the Balas for a couple of weeks and I have a question about tank
mates/tank size. I thought I would get a Rainbow Shark and a couple
Clown Loaches and a Cory or something similar. But I'm afraid the
tank is too small for that group of fish. Is my tank even big enough
for the three Balas? <The Balas will easily reach sizes of around 12
each so you wont want to add more than another 15-20 of adult size fish
to this tank, less would be better. The Clown Loaches can reach an
adult size of around 11 each so these are not recommended unless you do
get a bigger tank. The Corys and Tetras stay pretty small so should be
OK if you go with just a few of each. The Rainbow Shark can get to
around 6 so that one is kind of iffy.> I sort of wish I had made the
tank a community of African Cichlids, but on the other hand the Balas
are the reason I decided to keep fish in the first place. I'm
looking for a bigger (used) tank. I'm considering putting the Balas
in a bigger tank and converting the 75 to Africans. Does this make
sense? Any suggestions? The Balas are only about three inches at this
point. Thanks. --Charlie <Putting the Balas in a bigger tank and
going with Africans would be a perfect solution. Ronni><<I
would not place minnow-sharks with African Cichlids.

Bala
Sharks In a Planted Tank - 03/12/2006 Hello Again, I wrote
about this time last year with questions about filtration for 150 gal
aquarium in which I was overwintering my 2 pond fish, a 12 in goldfish
and 15 in koi. I was (and still am) using a Magnum 350
canister, a HOT magnum filled with bio-media, an Emperor 400 and 3 400
gph powerheads pushing the UG filter. I siphon 50 gal of the
water each week using a python gravel vacuum and stir up the gravel so
the filters can take out the suspended waste. When I wrote
last year I was complaining about not being able to keep up the amount
of waste generated by the fish. Bob Fenner suggested I clean
the filters more often and add a couple of box filters and an air pump
to aid in filtering the debris. I added the filters and a
Luft air pump. When the weather warmed up enough to take the
fish outside, I decided they were too big for my 400 gal stock tank so
I gave them to friends who had in-ground ponds and I got a couple of
smaller goldfish. Naively, I figured my filtration set-up
would be able to handle 2 goldfish. I brought them inside in
Oct. and have been faithfully cleaning the tank and the filters as
described above (I swear) and am back with the same problem, I cannot
keep up with the waste from the goldfish, they are between 6 to 8
inches. SO, I have decided to give up on keeping
the goldfish in the aquarium over the winter. I may give
these fish to my pond friends and get some 'mosquito' fish for
my stock tank. Now I'm getting to my question - I have
thought for a long time that Bala sharks are very attractive fish but
never had a tank I thought was big enough to house
them. Several years ago I had a 75 gal plant tank with lots
of tetras and had good luck, and since I have decided to forego the
goldfish I am considering a tropical freshwater tank
again. But before I invest in more lighting and live plants,
would you tell me whether 3 Bala sharks would create the same trouble
with waste as the goldfish. I have been thinking
about having a school of 12 to 15 rasboras, several Siamese
algae eaters and 12 - 15 kuhlii loaches with 3 Bala
sharks. But I don't want to get it all set up and not be
able to keep up with the waste. I kept tetras for
many years and really do the maintenance I have
described. However, with the goldfish, the pleasure factor
is greatly outweighed by the unsightliness of the
waste. Would you be willing to give me feedback about this
plan or modifications that would make it feasible? I'd
sure appreciate the help. Thanks a lot. Kerry
< Bala sharks get big. I have seen them personally up to 18".
These of coarse were very old but very well cared for fish. They would
be like a bull in a china shop disturbing the planted tank just by
their movements. A better choice would be some roseline sharks. They
have a similar body shape but a nice red streak to the body. They
don't get too big but make a very nice addition to a larger planted
tank. they are expensive but the prices are coming down. They would
definitely be easier than a goldfish tank.-Chuck>
Bala
sharks... sys., dis. 8/18/06 <<Hello. Tom
here.>> I have a fifty-five gallon freshwater tank that is three
years old and stable. I'm having a heck of a time introducing new
Bala Sharks. I've got a healthy one in the tank that is over two
years old but when I introduce new ones the new fish develop white
scales and their eyes fog over. Temp. is 82 degrees and the PH is 6.8.
Everyone else seems happy except the lonely shark. Any ideas?
<<Strikes me as an acclimation issue, Bill. Have you asked your
shark source as to what their parameters are? If your two-year-old is
doing well, I suspect that you're introducing the new ones too
quickly into an environment they aren't ready for. Far less likely
a problem with temperature than it is with the pH. Get this information
from the store and I'll bet you'll discover what the problem
is.>> I used Mela fix to help but to no avail. <<Not likely
to be at all effective if the cause is pH shock. Tom>>
