Don't worry this has nothing to do with hybrids,
First off red devils will not fit in a 55 for any length of time same goes for dovis, both fish will need a tank that is at least 24" wide.
I have read alot of posts lately that suggested putting fish that grow very large in small aquariums. So I felt that this thread might be usefull to people If we can get some accurate information on max growth rates of fish you have personal experience with, and the tank recomendations they will need as they reach maturity.
