With out the proper information given in your original post, it's really hard to figure out the issue you are trying to resolve, for us (The helpers). As stated by bassinmike85 we are here to help you out. Now, Your kelberi's are 8'', so, lets assume that they are 6 months old. In 6 months your kelberi's will be pushing 12-14''. So you might want to upgrade. As for the fighting part. Kelberi's are fighter as well as orino's (IMO/IME, the worst two out of the cichla that are available in the US). Xingu's I have no clue, I never owned them. But, any way's, Target fish and dither will help, if not solve the fighting issue. More activity in the tank the less your kelberi's will focus on each other.
