I just picked up a 6" vittatus on an impulse buy and now I am wondering how it will do with my tank mates. It is in my 230 growout for now as it's too small for my 450 gallon and it will eventually go into a 520 gallon when it's done. It is in the 230 gallon with an 8" RTG arowana,4 orino pbass,3 red neck severums,L330 pleco and and 5" armatus. What kind of problems do you think could arise with this combo?
