How big is your tank? Maybe try to find a tat. It's a red tailed payara, and I have one in a 125 with a VATF and a motoro ray. I have a 350 on the way for all of them. Tats are cool fish. I like them better than armatus
also do you know where i could find a tat? it really doesnt matter which one as long as its not a scomb, id really like one that will be around for a couple years
