You just need enof space and the right manered fish. I have my largest male (Pha Hon) in an agressive community take right now and he does just fine so do all the other fish in there. Tank mates are as follows- 12-13inch butacaferi talapia spelling is probably off, 13inch jag, 6inch green terror, 5inch blue jahanni, two other big as* africans that I dont know what they are one yellow one mango both are about 7inches, 11inch Jack Dempsey and one big as* cat fish 14inch or so. They are all living quite peacefully in a 180gallon. The Flower Horn likes to mess with the Budda the most, but they are of about equal size and both have nasty tempraments. The Budda will bow down but the FH will never even hit him. I think he just wants a respectfull submission from him! Haha. Anyone who says this can not be done is a dip Sh*t lol. I will try and post some pictures tonight. I just got my digital and I have been waiting for an oppertunity.
