I have a 3-inch female GT in a 36 gallon bow front. I also have a male kribensis, 3 tiger barbs, 1 pleco, 1 emerald cori, 4 black neon tetras, 1 rainbow shark, 1 silver dollar, and 2 angels. My tank has been up for 4 months now and is very fun to watch. The GT is the boss of the tank for sure, she will intimidate but has yet to hurt anyone. The krib is 2nd in command and keeps his distance from her. The rainbow shark love, and I mean loves to chase the 3 tiger barbs, other than that it does not bother any other fish. The 2 angels are not bothered by any other fish and they do not bother any others. The cori gets all the attention of the GT and the krib, no biting, just intimidation. The 4 black neon tetras just school together at the top and no one bugs them. The silver dollar just swims around ignoring what is going on around it. It is a really enjoyable tank to watch, no violence as of yet; however, I definitely have a feeling I will have to trade some of my fish in to my local fish store as they out grow my tank. Happy fish, happy owner, I love my tank.

I have a 4 or 5 inch green terror that I've had for a few years. About a week ago it had a small pinkish growth coming from its anus area which could look like male genitalia. Its now a bit bigger. It looks like intestines hanging out. Help please

    Could be a parasitic infection.

    It sounds like your GT is female and about to spawn. I could very well be wrong but that's what it sounds like.

    A green terror needs that size tank by himself.  He is a carnivore and is going to grow up and be about 12 inches long and as soon as the convict will fit in his mouth - it will be considered food by the Green Terror. 
  • Jeremy Roche - 2012-06-25
    That will work for now.  Just watch them as they grow.  Great thing about convicts is they can stand up to larger fish.

    Rule of thumb is one usuable gallon of water for each inch your fish will be as adults.  You have to subtract gallons for substrate, plants decorations etc.  Your tank is too small for the fish youhave.  The Green terror is a carnivore and as soon as he can fit another fish in his mouth - it will be food.  It is peaceful now but it will change - just not enough room and you have a carnivore in there.

Can anyone please tell me that I have kept a pair of green terror of 2-3 inch with a koi carp, about same size. And a betta, about 2 inch. Will green terror devour them or can live with them?

    A koi-carp is a COLD water fish. While the other two are WARM water fish. You can kiss your betta goodbye...
    It's always handy if you inform yourself a bit about a fish before you buy him.

    No. :)
  • Samuel - 2011-07-08
    Yes, as long as it's alone. In fact it may be better.

    No. Green Terrors require a 75 gallon if kept alone. They reach a decent size.

I just got 3 GT's last week and they already laid eggs! I'm new to raising fry and this all happened so quickly. Could you give me some pointers? I want the fry to successfully grow up but there are other fish in the tank, an Oscar and 3 Jaguars and a Pleco an all the fish are around are about 3 inches long including the GT's. I had no idea they could breed being this small but do you think the eggs will survive being in a tank with the other fish? I have no other tank to remove the other fish to at the moment either. Thanks if you reply!

    Congratulations. That had to be a shock. I am more a bird person than a fish person, but I have had fish. To the best of my knowledge an Oscar or a Jaguar will eat anything. I have no idea how you can remove the eggs or even the other fish (especially if you just have the one tank) but is there a way that you can use a glass partition to separate the eggs from the other fish? Can you use anything that won't inhibit the filtration system but yet protect the eggs? From the information in Animal World, the parents need to be with the eggs so possibly screen so the filtration system continues to work. The information on the Green terror laying eggs is in the next sentences so you need the parents with the eggs. However, you don't know if both the female and male are mature so if the eggs are fertile.

    The Green Terror are egg layers. Get several juveniles and allow them to pair up. The parents will clean off a flat rock to spawn on and will lay up to 400 eggs. They will care for the young. Feed fry crushed flake and fry food. See a general description of how these fish breed in Breeding Freshwater Fish.

    Good luck and what a surprise.

Hello, I just wanted to say that this fish can be a lot less aggressive than people make them out to be. I have one, it's a male (you can usually tell by how vivid the colors are and later the hump on the head) he's about a year old at least, about 6.5 inches. He's in a 46 gallon tank with smaller semi-aggressive fish. He does not go after any fish at all. Other fish are intimidated when he comes around, but he doesn't try to nip at anyone. This is also a very hardy fish too. I have had this fish since the beginning and he lived through some possible new tank syndrome and a recent bad case of ich in the tank. I love this fish. My first fish (besides goldfish) and I am thinking hes going to live for a long time. I would also recommend some sort of cave or something for this fish. He really likes to go in there when something spooks him.

    It's only when you have a couple and they mate, that the A. rivulatus shows his true colours. Besides, with the A. rivulatus a lot depends from one individual to the other. I have a friend who had a couple of A. rivulatus and the male killed about every fish he had. Even those, who had twice its length, weren't safe from him.

First of all keep it up for your site! Very interesting and informative!

I have an adult green terror / Gold Saum and I still cannot tell if it is a male or a female. No nauchal hump is present but there are traces of a 'bump'.

I have tried venting but what I did till now is just visually try to vent without catching the green terror as it has its tube protruding 1-2 mm out. In appearance it has a cylindrical base but it does come to a rough point, but it is not a sharp point. Also I have noticed that it points at a 45 degree angle from the fish.

Can you help me in sexing my green terror please?

Any help is very much appreciated.

I had a beautiful Green Terror named Quervo. The story of how I bought Quervo is interesting, I've had every kind of fish and consider myself an expert when it comes to water quality, compatibility, equipment use, medicines, etc.

To change things up, I picked up a small 5" African Lungfish to put it in a 75 gallon tank. While Ramses was small, I tried different fish to see if they would get along much less survive and I quickly learned the answer would be no.

I tried an Arowana, Jack Dempsey, and many others. I even put in two Leaf Fish thinking the Lung Fish wouldn't see the 'dead leaves' floating and if he did, would ignore them. Nope, he got them too.

The last one was Quervo, the striking Green Terror. In a 75 gallon with a 5" Lungfish, I was told (and thought) most any fish, especially one swimming in the upper part of the tank, would do fine.

The first day they were together was uneventful. The Lungfish knew there was company and made a couple of quick moves but the Terror was too fast and aware of it's 'company'. The second day, I watched the Lungfish move like a missile and push the Green Terror so I quickly prepared the 30 gallon for Quervo though it would take a couple of days for water quality to be set.

That night, Ramses struck Quervo and bit a piece of Quervo's back. I though it was done, weak swimming, lethargic, etc. Instead, he came back and did so with vigor. His back seemed to regenerate and I kid you not, it had a certain swagger as it swam by the Lungfish and maneuvered itself in a confident manner.

I ended up leaving it in the tank and honest to God, they became the best of tankmates. Anything else I added, one of them would take out. They both grew to where they went into a 180 which is where they stayed for years.

To this day, I have a special affinity for Green Terrors.

    If you informed yourself a tiny bit, before buying a fish, you should have known that the Lungfish is VERY territorial.
