Neon Tetra Compatibility 6/21/12
Hi Crew,
I have the following fished in my 50 gallon aquarium. I like neon tetras
and am planning to buy around 30 neon tetras to add to this lot.
<Nice. Now, do remember two things about Neons. Firstly, they need soft
water and don't live long in hard water. They also need quite cool
water, 22-25 C. You've probably read about them being disease-prone?
That's because LOTS of people keep them in hard water and at high
temperatures.
They are also very small, and big fish either eat them or take so much
food the Neons can't eat.>
Qty Type
3 Molly
<Nope; needs hard water.>
2 Silver Shark
<Too big; will eat them.>
2 Comets
<Too big.>
4 Rosy barb
<Too big.>
4 White skirt tetra
<Possibly.>
3 Pearl gourami
<Yes, but does prefer warmer water, so you'd need to keep the tank at
24-25 C to keep both species happy.>
1 Dwarf gourami
<Yes, but again does prefer warmer water, so you'd need to keep the tank
at 24-25 C.>
10 Rainbow fish
<Depends on the species; most are too big, but they're not actually
aggressive, so in a big aquarium might work.>
1 Neon Tetra
2 Cory Cat
<Most species work EXTREMELY well with Neons; the exceptions are those
with unusual water preferences, like Corydoras sterbai (which needs
warmer water) and "Corydoras" (really Scleromystax) barbatus (which
needs much colder water).>
a. Can you please tell me which of these fishes listed above are not
compatible with neon tetras.
b. Can you suggest me some other fishes that are compatible with neon
tetras
<Good companions for Neons are: almost all Corydoras catfish, Kuhli
Loaches, Bristlenose Plecs, X-Ray Tetras, Red Phantom Tetras and Cherry
Barbs. Really, anything peaceful, small (2-5 cm), enjoys soft water
(2-12 degrees dH), and is happy in cool sort of water (22-25 C).>

Thomas

Jumbo Neon Tetras
Neons Eaten By Which Fish? 10/14/10
Question: We have an 80 gallon tank, with an old upside down catfish 5
inches long, an old striped Rafael 4 inches long, 2 new severum 2 1/2
inches long, 2 new angel fish about 2 inches long, and we had 15 jumbo
neon tetras about 1 inch in size that did well for three weeks and have
now been slowly eaten. Who would be the culprits in our tank? Could we
be successful with the jumbo Neons if they were 2 inches long?
< Real upside down catfish are only a couple inches long. There are
many Synodontis species that swim upside down and could be called
upside down cats. The cichlids could be killing them and the catfish
picking off the scraps. Larger fish would no be eaten right away but
still could be killed..Neons really do better in a tank with fish their
own size.-Chuck>
Question about Bettas and neon tetras,
incomp. 7/1/10
Hello:
<Ave,>
I was wondering if it is ok in the long run to keep a Betta in a twenty
gallon long with 16 neon tetras?
<No. Neons need cooler water (22-24 C for Neons, versus 26-30 C for
Bettas) and in any case Neons view Betta fins as food.>
The Betta has been in there for two weeks now and the Neons are not
nipping him,
<So far...>
also the Betta is ignoring the Neons. He is a timid Betta and never
flares nor blows bubble nests. I am thinking that the Neons would
probably need cooler temps than the Betta
<Indeed. Neons have a notoriously short lifespan when kept either
too warm or in water that is too hard, and problems with Neon Tetra
Disease seem to be an epidemic among farmed Neons. I've basically
given up with them, and I consider myself an expert fishkeeper!>
Also I am wondering if the Betta may freak out one day weeks or months
from now and go after them even if he is timid??
<Possibly. You can keep Bettas in community tanks, but it's
hard, and requires very careful planning. I'd be concentrating on
species that feed from the substrate, such as Kuhli Loaches or Dwarf
Corydoras, perhaps Cherry Shrimps or Dwarf African frogs if you want
oddballs. Neons and other schooling fish tend to work poorly with
Bettas.>
Thank you!!!
<You're welcome. Cheers, Neale.>
Guppies and Neons, env. incomp.
6/18/10
Hello:
Sorry for bothering you again.
<No problems.>
I have a tank with two guppies and eleven Neons and I was just
wondering if I should give the guppies away since the tank temp is
usually about 73-74 F?
<Indeed, and Guppies also need hard water which Neons can't
abide. I'd tend to look at your water chemistry first and see what
you have. If you have soft water, the Neons are the obvious fish to
keep. If you have hard water, the Guppies will do better. Once you have
the right fish, it's easy to set the heater up or down as
required.>
I remember you mentioning that guppies would rather around 82 F and I
am worried that they are stressed.
<"Stressed" isn't perhaps the right word here, but
fancy Guppies at least are more prone to diseases when kept towards the
cooler end of the temperature range. If yours are fine, then you
needn't worry, but if you find you're constantly battling
Finrot and Fungus, then temperature may be an issue.>
Thank you!!!
<Cheers, Neale.>
Aggressive Neon Tetra 6/6/10
Good morning from the UK
<Hello,>
I have a 25 gallon tank (fully planted and cycled). It currently homes
5 neon guppies (1 male, 4 female), 5 panda Platies (1 male, 4 females),
3 cherry shrimps and 9 neon tetra (new).
<Not a bad combination, provided the water isn't too hard. But
Guppies tend to want warmer water (around 25-30 C) than either Neons,
Platies or Cherry Shrimps (22-25 C). In theory Guppies should be fine
in water that cool, but many of the fancy Guppies are delicate and
become prone to diseases when kept that cool.>
I've had a few fry appear (some have been moved to a nursery
tank).
However, I wanted to check the behaviour of a couple of the Neon
Tetras.
They are the largest of the nine and appear to hover around the planted
areas where the fry are and aggressively chase away any of the other
Neon Tetras. Is this normal?
<Can be.>
Is there anything I can do
<Not really, beyond adding a few more.>
or should I just let them carry on (I don't see any fin nipping
yet)?
<About all you can do.>
Many thanks
Patrick
<All schooling fish are hierarchical, and within that group a
certain amount of aggression is "par for the course".
Isolating the dominant fish in a bucket, moving the rocks and plants
about, and then reintroducing them into what they perceive as a new
environment can help. Adding more Neons can also help by altering the
social structure and spreading out any aggression. But usually
schooling fish settle down eventually. Cheers, Neale.>
gouramis (advice) 4/25/10
Hi I just have a quick question.
I have recently bought a 70L tank, about a week later (as per store
person instructions) I decided to buy some fish, namely: 2x
dwarf gouramis (both males 90% sure one flame coloured
and the other blue and red stripes) and 5 neon tetras.
<Neons and Dwarf Gouramis make poor companions. Neons need fairly
cool water, 22-24 C/72-75 F. Dwarf Gouramis must be kept warm, around
28-30 C/82-86 F. Any conditions good for one will be stressful for the
other. This is clearly stated in any aquarium book, so as always, read
up on the needs of your fish prior to purchase.>
All the water was tested beforehand and was fine, my PH however was a
little bit on the high side- 7.2 /7.4
<This pH is fine. More aquarists cause problems by adding those
often-lethal pH up and pH down potions they convince themselves they
need. Both these species will be fine at 5-15 degrees dH, pH
6-7.5.>
I have noticed that males can get a bit territorial , and do nip and
chase each other a little bit. As well as- they do funny swimming up
and down ( looking over previous articles, I see this almost a normal
behaviour....)
<Yes, your aquarium is too small for two male Colisa lalia.>
My question is , can I add a 3rd fish - another
Gourami ?
<Nope.>
And if I can, should I the fish be a male? or should I get female?
<A male and a female might be okay in this tank, possibly a male and
two females. Two males is risky, and two males and one female would end
up with some poor female pestered to death by the aggressive
males.>
Or should I get a 3rd different kind of Gourami, I'm not sure if
this make any difference?
<Your aquarium is too small for any more Gouramis. Males of all
species are territorial.>
Or perhaps another different species altogether?
<Read:
http://www.wetwebmedia.com/fwsubwebindex/dwfgdis.htm

http://www.wetwebmedia.com/ca/volume_5/volume_5_3/stocking.htm
http://www.wetwebmedia.com/FWSubWebIndex/fwlivestk.htm
Your aquarium is already badly stocked and badly overstocked. Instead
of randomly adding fish and hoping for the best, choose livestock that
will be compatible in the long term.>

Female Betta and neon tetras, incomp.
2/16/10
Hello:
I have a 10 gallon tank with one female Betta in it at the moment. The
Betta is almost totally white, which I guess is rare. She is also very
passive and barely even moves around. I was thinking of putting a few
neon tetras in there, but I am wondering if she would go after them.
Would this set up be safe?? Thank you!!
<Neons and Bettas aren't a good combination. For one thing,
Neons prefer cooler water, around 24 C, whereas Bettas need things
comparatively warm, around 28-30 C. So anything "just right"
for one species would be stressful for the other. Bettas are also
nipped by Neons. Yes, this is normally observed with male Bettas, but
why risk it? There are many better choices for female Betta tankmates
out there. Cherry shrimps, Kuhli loaches, perhaps even Boraras spp.
Dwarf Rasboras. Cheers, Neale.>
Worried for my fish. Molly-Neon mis-mix, no reading, full
moon stuff... 11/18/09
I have one Dalmatian Molly, one gold molly and 4 neon tetras together
in a large tank, it has plenty of plants.
<Do understand Neons and Mollies are not compatible. Neons need cool
(around 22-25 C) water that is soft to moderately hard, and not too
basic (5-15 degrees dH, pH 6.5-7.5). Mollies by contrast need much
warmer water (around 28 C) and the water must be very hard (15+ degrees
dH) and very basic (pH 7.5-8). They almost always do better when some
marine salt mix is added, at a dose of between 3-9 grammes per litre
depending on the tankmates and plants. All of this will be quoted in
aquarium books, which is why we recommend you read a book before buying
any fish.>
I have recently found out that both my mollies are male (thank
goodness) My concern is, for a few weeks now my gold molly has been
getting fatter very ball like and can no longer swim, he sits in one
spot all the time on the bottom of the tank, my Dalmatian molly appears
to be fretting for the gold as he is always going over to him and
trying to lift him off the bottom of the tank, he is continuously
trying to push him up, and when he gets the gold up so far the gold
just sinks straight to the bottom of the tank again,
<He is not "fretting" but being aggressive.>
His breathing has become more erratic and I've noticed his fins are
getting faster in movement but he's still not getting anywhere. He
has also stopped eating now and I'm worried he is going to starve
as it has been a few days.
<What are the water conditions? As stated above, Mollies need very
specific conditions to do well.>
I have medicated the tank with a multi purpose treatment but it has had
no affect on him.
<Useless approach. Diagnose the problem, then treat. Imagine if your
doctor couldn't be bothered to check your symptoms, and just gave
you the first pot of pills he pulled from a drawer!>
I separated him from the others but he looked panicky and was
constantly pushing up against the side, while he was in the other tank
I noticed his anus was very white and looked like it was protruding out
of his body like a hemorrhoid.
<Is not this.>
I'm concerned for my other fish as my Dalmatian molly is more
active then usual in what looks like a concerned manner. and one of the
Neons seams to be becoming rounder in the tummy and becoming slackish
in its movements.
<Check water quality and water chemistry. For both species, 0
ammonia and 0 nitrite are critical. But since Neons and Mollies need
completely different water chemistry, it's unlikely (i.e.,
impossible) to keep both species 100% successfully in the same
aquarium.>
Id appreciate any advice you could give me as I don't want to loose
any of my fish.
<I'm afraid they're doomed. You've thrown two
non-compatible species together, and without giving me any actual data
in terms of water quality, water chemistry, or temperature, I have no
idea what precisely is going on here.>
I have looked all over websites trying to find an answer but nothing
that I can find displays any of his symptoms together.
<These sound like generic "get me out of here" symptoms
exhibited by fish being maintained in a poor (or the wrong)
environment.>

Male molly, sore eye, oh my. Ongoing, child, mis-mix with
Neons -- 02/19/09 Hi, I am just writing to say my Neons
are now in my big tank (2ft tank) with my other fish and seem to be
doing fine my small tank has my to tiny baby guppies in it for the
minute. My male molly has been nipped on the eye by a neon <Mmm, not
compatible... behaviorally or environmentally. Please read re the water
quality needs of these two species> because he got in its way when
it wanted food it has swollen and looks so sore but I was given some
Myxazin to treat it none of my other fish seem to have any other
problems and seem to get on fine with my Neons I'll just remind you
what fish I have, I have 3 guppies (1 adult very pregnant female and 2
unknown babies), a breeding pair of Dalmatian mollies, a breeding pair
of platies, 6 Neons and 1 Sailfin Plec. Thanks alot <No such
word> ,Alishia. <Neons should be moved elsewhere>
Neon Tetras And Serpae Tetra, incomp.
5/5/08 Hello there, nice to be back! I have my problem with my 9
neon tetras and 5 Serpae Tetras. First week after I buy the Neons the
Serpaes are not doing anything to the Neons, they don't disturb
them. <Yet...> Yesterday I saw one of my Neons has no tail then
one Serpae attack the neon and bite the neon's tail. <Ah, there
it is.> I'm shock when I saw it, and until now I can't
imagine the worst thing my Serpae did. I think of possible solutions,
and it came to my mind that if I remove the Serpae tetra (3 of them)
will the aggressiveness will be minimize, I will just remain one male
and female. Is it ok? <Nope. Serpae tetras, as I point out
repeatedly here at WWM, are not community safe. They eat fins and
scales in the wild, and also have a "feeding frenzy"
behaviour that means they lunge at anything and everything when
feeding. Mixing Serpae tetras with anything other than more Serpae
tetras is not a good idea. Period. End of discussion. They're great
fish on their own, but were the very first fish I ever kept way back in
the early 80s, and I learned my lesson the hard way.> please give me
the right solution. My tank is 10 gallons, planted, and an Amazon
blackwater layout. <Neons need cooler water (around 22 C) than
Serpae tetras (around 25 C), so aren't really compatible anyway.
I'd get rid of the Serpae tetras, since a 10 gallon tank is too
small for them. Keep the Neons, let the temperature drop, and if you
want obtain some suitable tankmates for this sort of tank, e.g.,
Corydoras habrosus.> Hope you will reply soon. Thanks and more
power! <Hope this helps! Neale.>
Schooling Advice... Neon
Tetras 2/10/08 I recently e-mailed you guys about my
school of diminishing neon tetras. After hearing from you guys that
Neons are poor quality most of the time in large stock and from my own
experience, I think Neons are just too much of a hassle and a waste of
money because of there very short longevity. Currently there is 1 dwarf
Gourami, 2 blue gouramis, 1 gold Gourami, and 4 rainbow sharks in my 55
gallon aquarium along with about 5 remaining neon tetras. Here's my
question though. What do you think would be a good schooling fish. I
was thinking about tiger barbs, but if you can think of something
better that'd be great. I plan to just put my remaining Neons up
for adoption at the petstore as I did with my crayfish. Thanks for you
help and advise. <Jonathan, given you were keeping crayfish with the
Neons, I'd not be too quick to blame the Neon's demise on poor
health. In addition, it is absolutely essential you eliminate
environmental factors before apportioning blame. So do a pH test and a
nitrite test, and check your filter is still working properly and not
clogged up. Obviously if the water isn't that great, *any* new fish
you add are likely to suffer. Fish that have been established in a tank
for many months will often seem happy enough in such tanks because
they've slowly adapted to those conditions. But any new fish will
be used to the water quality/chemistry at the retailer's tank, and
will get stressed or killed by being dumped in entirely different
conditions in your tank. In any case, Tiger Barbs would be a poor
choice for a tank with Gouramis because Tiger Barbs are fin-nippers. So
to are Serpae tetras, Black Widow (Petticoat) tetras, and several other
small characins. Read up on any species carefully before you make a
purchase. I happen to consider Bleeding Heart Tetras among the best
all-around characins: they are pretty, quite big, constantly chasing
each other but completely peaceful towards tankmates. They are also
hardy and too fast for aggressive or nippy fish to bother (mine live in
a tank with puffers and have NEVER been nipped). Australian Rainbowfish
are also very reliable choices, especially if you have hard water.
Cheers, Neale.>
Betta Compatibility with Neon Tetras 1/7/07 Hi,
<Hi> Great web site. <Thanks> I am in the process of
starting up the first cycle in my 30 litre heated BiOrb with 2 neon
tetras and 1 algae eating shrimp. <Neon tetras are pretty sensitive
to water quality, keep a close eye on it.> So far so good and I am
now planning ahead to see which fish I would like to add and when.
Could I add a male Betta/fighter in a month's time? (when chemical
levels are good etc..) <Not a good mix, have seen Bettas try to eat
little Neons, plus their water quality needs are pretty different.>
If so and if he is settled could I then add more neon tetras at a later
date? Thank you very much in advance, Rob <Chris>
Platy & Guppy Questions... and Neons in the mix
2/22/06 I'm new to the hobby, but your site has been quite
helpful. I have a couple of questions about the health of my
fish and I hope you can help. I have a 10 gallon tank this
is well filtered, heated to about 79 F, and planted as my main tank and
a 2.5 gallon hospital tank. I have 7 guppies, 2 male and 5
females; 3 platies and 13 platy fry that are 2 days old and doing very
well; 3 neon tetras, a Chinese algae eater and 2 bamboo
shrimp. I know I have a bit too many, but water quality
seems to be pretty good and I test it at least every other day and I
have another 10 gallon being shipped. When I first brought
the platies home, one had a white rectangular wound on her back so she
went straight to the hospital tank where she is now, and gave birth 2
days ago, and the white stuff has spread around her a little, but its
not spotted like Ick is and appears to have some trouble swimming in
the main tank. Also in the hospital tank is one of the Neons
who has some gill trouble - loss of gills or the cover, <Happens>
but it appears to be slowly returning to a more pink color and one
female guppy who has gotten progressively worse, she has some raised
scales, large white growths. One of the guppies in the main
tank also has a few scales that appear almost like a shed skin coming
off, but they don't appear to be getting any worse. None
of the other fish seem to have any trouble, but I'm not sure what
to do about the fish in the hospital tank or the one guppy with the
"shedding" in the main tank. Any help or advice
you can offer me would be greatly appreciated. Thanks. Arlie
Hubbard <I would separate (when you get the new ten gallon) the
Neons, read re their water quality (softer, acidic, warmer) and the
livebearers... and keep their environments to their liking... This is
all that is needed here. Oh... and keep an eye on this Algae Eater...
often trouble with other fishes. Bob Fenner>
Angel Finds Neons a Tasty Treat (4/22/04) Hello - I cannot
thank you guys enough for the awesome website! <It's an honor to
play a small part. Steve Allen here tonight.> I've had a planted
29 gallon freshwater tank running with only an Angel (about 4 inches)
and a balloon bellied molly for quite a while. All of the other fish
died of velvet and these two were the survivors. Today I decided that
the tank could use some new inhabitants and I really wanted small
schooling fish. I purchased a 3 pack of neon tetras and finished
acclimating them about 2 hours ago. Unfortunately my 3 pack is now a 1
pack and my Angel fish now has a pot belly, so he got a very colorful
snack. <Tasty too.> I really want to keep some sort of schooling
fish in this fairly small tank. My question is if I buy more of the
neon tetras will they have a better chance of survival in a bigger
school (maybe 6-9 of them to create confusion) or am I just buying an
expensive snack? <Number two. The Angel will pick them off
one-by-one in that small tank.> Are there other small schooling
freshwater fish that are better at escaping or a bit bigger so they
wont fit in the angels mouth? <Not small ones. You could put maybe 4
or 5 somewhat larger tetras such as Lemon or Serpae. These ought to be
OK, but since your Angel is already rather large, start out with
near-adult size ones. Another possibility would be Golden or Cherry
Barbs, but these could get a little too big. The angel will continue to
grow somewhat bigger, so you need to be careful not to put too many
other fish in there.> Thanks in advance for the advice :) <Hope
this helps.>
A Betta to the Mix? Hey crew. Do you think a male Betta could
peacefully live with my 9 neon tetras and my 3 platys in my 10 gallon
freshwater planted tank? Thanks! <Nope, sorry but two problems here.
The dozen fish you have now are about the limit of a 10 gallon. And the
Betta will turn a small Neon into lunch. A big (?)
