Green terror, not eating, parasites?
Good afternoon, crew.
I've had an Andinoacara rivulatus for over three years, had it since it
was about an inch. He's about 7 inches right now. A proud father, he's
in a 50 gal with its partner. They get along fairly well.
He stopped eating about 3 days ago, normally a glutton and i mean a fish
which would eat until it was swollen like a balloon, i am wary.
<First thing, check environment. Moderate water changes and extra oxygen
will often perk things up if fish aren't ill but merely stressed by
something in the tank. Also try slightly cooler water than usual to see
if that helps, with low-end tropical temperatures between 22-24 C
probably ideal for this species.>
I've started to do small water changes ( 15%) daily as the green terror
tank water had parameters of 6.0 Ph and 4 Kh.
<A bit low for this species. More neutral, medium hardness water is
probably ideal for this species. On the other hand, given its age, any
water chemistry changes should be made slowly.>
Fairly soft as it's partly in my yard and rain falls on it. Tap comes
out at 10 Kh and 8.0 Ph, so water changes are small. ( he's lived half
his life in tap and half in this rain/tap mix).
I noticed trans-lucid, stringy poops out of him ( not white nor yellow,
but transparent), he's alert, is still chasing the female ( they lay
eggs every 2 months and its about time now) colorful and responsive, he
chews food but spits it out. I checked his body for flukes or Hexamita
and none of it are present. So I'm not sure if it's parasites or maybe
<Unlikely to be parasites if you haven't added anything new in the last
few months. That said, Hexamita may well be latent in most farmed
cichlids, so treating as per Hexamita isn't a bad idea.>
Too soft water?
Thank you very much, i will be waiting for your response.
<Hope this helps, Neale.>
Green Terror Breeding
Green Terror Cichlids Trying to Breed 11/17/11
Hello, Great site!
< Thank you.>
I have a question about the breeding rituals of Green Terrors. I have a
male (5 inches) and female (3 Â½ inches) in a 75 gal tank.
I have had them for about three weeks. I run a 1500ltr/hr. canister
filter which is well maintained and does a great job. I do a 25% water
change(through vacuuming the gravel) twice
weekly. My water tests show a ph. of 6.7, ammonia and nitrites of 0 and
nitrates under 5. I run the temp around 78F. I feed them a small amount
of food twice a day. Their diet consists of cichlid pellets and blood
worms (as a treat). They also get the occasional cricket or other live
insect I catch in the garden. My female and male have been doing the
breeding ritual for about two weeks.
Shaking, nipping (no damage) with the male following the female around
constantly. I made her a cave to hide in and she recently laid her
first batch of eggs.
Unfortunately I missed it and didn't see if the male managed to
fertilize them or not. The female is now extremely aggressive towards
the male, not letting him anywhere near the eggs. With this behaviour
is it likely that they are not a pair after all, or is this normal?
Whilst my male is normal extremely aggressive, and quite a bit larger
than the female, I'm also worried she may injure or even kill him
if this behaviour continues. What are your thoughts? Regards, Matt
< Young cichlid pairs sometimes take a few tries to get it right.
She now has a clutch of eggs and is not to sure what to do. Watch the
tank closely and see if the eggs hatch in a few days. If the male is in
danger he may need to be removed.. When the fry become free swimming
they can be siphoned into another tank and fed baby brine and finely
crushed flake food.-Chuck>
Green Terror with lumps on body 6/15/11
My Green Terror has developed a couple of lumps on its body at
around the abdomen. Other than that, its behaviour is quite
normal, ie eating well and very active.
Melafix hasn't helped.
From the attached picture, can you tell what it is? Would it be
Lymphocystis or something else?
<Can't tell... may be parasitic, developmental... need to
know re foods, tankmates, system... Put the two words:
"Cichlids Lumps" in WWM search tool (linked on every
page) and read the cached views. If nothing further, this
exercise will grant you insight into the sorts of data we're

Thanks for getting back to me. Sorry, I didn't include the
tank parameters as I thought the picture might point out what it
Ammonia = Nitrite = 0
Nitrate = 10

Green terror juveniles growing out in a 55 gallon -
Green Terror Cichlid Growth Rate
Hi Crew I have 7 Green Terror juveniles growing out in a 55 gallon
They are approx 4cm long at the moment. I plan to pick out a single
male from the group. How long do you think I have before I will have
problems with aggression and need to decide which one to keep? Cheers
< Many variables will determine how fast your cichlids will grow.
First is temperature. The higher the water temp, the quicker they will
grow. Second is food. The higher the protein in the food the quicker
they will grow.
Third is nitrogenous wastes in the water. The cleaner the water the
quicker they will grow. So at 82 F with a high quality food with 40%
protein and keeping the nitrates under 20 ppm, I would assume you
should see six to
eight inch fish in six months. Keep in mind that the larger they get
the more food they will need and more waste they will produce. As they
grow the water may need to be changed more often and maybe in larger
Green Terror Questions
Green Terror Growth Rate 5/18/10
Hello, First of all, this site is outstanding! You guys do a
< Thank you for your kind words.>
I have a few questions about my green terror (gold saum I
believe) and have had it for about 10 months. In that time it has
grown from about 2 inches to about 3 inches. It just recently got
moved from a 29 gallon to a 55 gallon. And it has always been by
itself since I got it. I assume that this is a fairly slow for a
growth rate, so I am curious what (if anything) should be
done...or is this a normal rate of growth?
< Your green terror is way behind a normal growth
I have always done 25% water changes weekly, and have gradually
moved up to about 50% water changes. I feed it Hikari Gold
Cichlid Pellets, and water have been 74 degrees. Ammonia and
nitrites have been 0 and nitrates have been less than .20.
< Jack the water temp up to 80 to 82 F. The protein in the
food should be over 35% and could be up to 50% if done
Also, I was wondering, would any tankmates be possible?
< Not in a 55 gal.>
I am assuming not, but thought I would ask. The fish come out and
swims around, but is still pretty wary of me being
around...sometimes when I walk by, its little gills flare out and
it charges the glass, but most of the time it
stays put or hides, but then comes back out. It is not that shy
at feeding time though. Is this behavior normal for a fish this
< Adding some dither fish will encourage him to come out
Perhaps I am just used to Mr. Orange (my red devil cichlid...it
his own tank of course) but it seems kind of timid. Also I have
attached a picture, is it possible to tell if it is a male or
female? It has been 10 months and it still does not have a name!
If there is any other info that may be helpful, please let me
Thank you for your time, Kelly

Re: Green Terror Questions
Dither Fish For a Green Terror 5/19/10
Thank you very much for the information, Chuck. I originally
thought it was a female, because the fins were not that long, but
I do see what you are talking about and perhaps it will get more
obvious as he gets bigger. I will gradually work the heat up to
the 82-84 range for a while and see if he bulks up. Could you
please recommend any good
dither fish that are native (or close) to the Ecuador/Peru
<Go for a group of six silver dollars. they are fast and
If not, would a few rosy barbs be good?
< Rosy barbs would be ok if they were the same size. The
silver dollars get big and will grow with your green
What are my options (if any) for a catfish, like the Raphael
catfish or something other than a Pleco?
<Once again these would be OK if they were the same size. As
the green terror gets bigger it will probably bully the smaller
I do understand that this is an aggressive fish and may be a
single fish in the tank...I definitely am not trying to throw too
much fish in the tank and most important is the health of my
green terror. I am good with single specimen tanks, just curious
about any possible options. Again, thank you very much for your
< It is called a Green Terror for a reason, so there are
limits the possibilities of potential tankmates.
Re: Green Terror Questions
Green Terror Tank Size 5/23/10
Thanks again! I don't mean to be a bother or anything, I just want
to make sure I understand. Could you please let me know if I am correct
in understanding that the 55 is too small for the green terror to have
anything else in there with him, but if I wanted to add some dithers or
a carefully selected catfish, I would eventually need more than 55
gallons once they reach full size?
< A green terror male can easily reach 12 inches. Not much room for
I would rather keep him as a solo fish in the 55 than need to upgrade,
due to finances and not wanting to take the attention from the green
terror. It really is a beautiful fish.
< A beautiful fish that gets big and can very aggressive towards
other tankmates. I think your best bet is to keep him by
Re: Green Terror Questions
Green Terror Growth Results -- 06/09/10
I just wanted to give you an update and had a question about food for
my green terror. I gradually cranked the heat to 82 like you said and
have continued on with 50% water changes once weekly, daily feedings of
either Hikari Gold (The large size pellet with 40% min crude protein)
or occasionally frozen wet brine shrimp. So far in the three
weeks since doing this, he appears to have grown almost another
Also yesterday I just started adding Sera Fishtamin to his food once
weekly per the instructions. I am thinking about gradually adding some
bloodworms, krill or Spirulina pellets to his diet to help with color
and such. I really appreciate all the great advise, and I am sure my
green terror (Oscar the Grouch) does too. Thanks again!
< Glad to hear that you green terror is starting to grow. I would
not try the bloodworms. Some say they absorb toxins from the mud they
live in. -Chuck>
