like alot of others flowerhorns can be pretty unpredictable, i once had a female that i couldnt keep anything with. at present i have a large male that is in with trimacs, jags, loiselli, mayan, johanna pike,xingu pike. he is king of the tank and a good one....doesnt start anything and has never harmed anything. twisted penguin has seen him and the setup. he was raised alone and grown to full size before he was added to the tank.
