I've had a pair of green terrors for about half a year now. I love them. There used to be two females with the one male in a 60 cm tank. And without pairing up with either of them he still seemed to have fertilized each female's eggs after she had laid them. Finally I gave away one and the remaining two have paired up. They are now in a 300 litre tank with a pair of Geophagus brasiliensis. Each fish pair have their own territory and respect the others. They get on fine.

I have a breeding pair of green terrors which have only just bred. The male is about 8 cm long and the female is a little smaller. They bred inside the small pot I put in the tank. They are very aggressive fish and will attack any other fish just to defend their babies, no matter how big the other fish is. These are very beautiful fish and I would recommend them to anyone, even starters as they are very hardy fish!

I had 2 that I originally got at first, but had to give 1 away as they got older. I kept the larger of the 2. Now I put a smaller one in and I already have 13 babies that survived and are doing well. They laid 2 batches of eggs and the second I guess was fed on by the first batch. Green Terrors will lay their eggs on a smooth surface and after a couple days will move them frequently. Tthey get very aggressive and I'd suggest having another tank ready for any tank buddies as even plecos aren't safe (you will have a very messy tank for a while). At about 3 weeks I moved the babies into a 40 liter tank and they are growing very nicely.

I have a breeding pair of these beauties. They attached their eggs onto a lava rock in my 240 litre cichlid comunity tank. The female guards over the eggs, while scaring away any fish that comes too close. The male acts very laid back and does not attack any fish with intent to kill, even though he is just under 13 cm! Once the fry are visible, I will leave them for 2 days before transfering them to a special tank, where they will grow, fed on powdered food and artemia. The eggs shouldn't be removed from the tank while on the rock as it causes too much stress on both the parents and the eggs.

I think the green terror is an awesome fish. I have had one for about a year now, I think it's a girl because there is no bump on its head. My green terror is about 18 cm now. I have trained it to get petted by myself - I used its favorite food (beef heart) and hand feed it and every time I would pet it on the back and after a week I would pet it twice then 3, 4, 5 and after about 3 months she would just let me pet her without any food. They are so beautiful. This fish is very easy to take care of. I would recommend this fish to everyone if you have a 200 liter tank or bigger and some rocks, they tear up the plants.

Breeding advice: breeding green terrors is not a difficult task. However, due to the aggressiveness of the males during breeding, it should be kept in mind that the female should be as close to the size of the male as possible. Yes, males are bigger, however an older female can be placed with a younger male to avoid gross size disparity between partners. Also, a tank of at least 200 liters is a must.
