I'm not sure what to do with my cichlid tank. I spent an hour today watching the tank to see if I can find out what the problem is. I found it. The cute little blue kenyii I bought a few months ago turned bright yellow, as they are supposed to when sexually mature, is systematically killing each fish from weakest to strongest. He has a seizure whenever others are around (he used to just chase his own species, now he's hell bent on destroying all fish in sight) and attacks fish. The others are too scared to lock jaws or do anything but get out of the way, and he's getting in fin and body shots. The poor guy I QT
'd for a week is now on top of the tank, if he tries to swim and hide the male kenyii and
all the others gang up on him and force him back to the top. The problem isn't lack of hiding spaces, there's plenty to go around. Now one of the smaller yellow labs is getting skinny and acting strange. I don't know whether to get rid of the kenyii and just stick to yellow labs, or get rid of the yellow labs and try to find 5 female kenyii. Or, perhaps the cruellest is just let nature take its course and see who wins in the battle of the cichlids (I already know the outcome). Does anyone know, if I get 5 female kenyii, if the male will go after these too?
The problem is, I really like the color of the kenyii--the blue and the yellow, but perhaps the tank isn't big enough for them. The project I was thinking of for my cichlids will have to wait until the end of my semester at school, but in the meantime the rockwork leaves plenty of hiding spaces (I thought).
I should have stuck to peaceful schooling fish
