I got a 4" ish Butti once to keep with large cichlids like Oscar and others that were already in the tank. Went back to the lfs less then a week later and I ended up with very badly banged up fishes. Butti was chasing them mercelessly non stop. Biggest mistake from my part which i will never repeat again. That was my experience the choice is yours
I think I'll just grow the Butti out a lil in 55 and give it to my uncle. HE seems to be fascinated with the lil fish!
