I have a pair of kribs in a 20 gallon community that is not so slowly becoming a krib only tank. They are in breeding behavior and are harassing everything to death from the looks of it. I thought I had a disease outbreak but on watching the kribs, they are healthy and are chasing and attacking everybody else to submission and eventually death :sad . So far in the last weeks I've lost an albino dojo, 5 rams, about 3 platies. I've moved all my really nice fish that are left (the long finned albino bristlenoses) into another tank, but the bristlenoses are only other fish that doesn't seem phased by these kribs (I've left two regular bristlenoses in the tank, one male has one of the caves to himself). I thought these guys were supposed to be peaceful? I had a pair of Moliwes before and they got along with everybody, including rams. This pair seems to want to terminate everything in sight. Is this common? (hmmmm, maybe that's why the fish store had them in a lone tank?) They were so much more colorful than most other kribs I've seen too. What else can I put in with these guys if anything?
