Another tang stocking thread

[xtreme]

I would say the kole tang would be your "best bet". I've never had a powder brown so I can't really comment there. As mentioned the purple would do ok but would become the boss of any other fish of similar shape or size. I would advise against the powder blue and they are tougher to keep and would also require a tank bigger than 4' long term, mine never stops swimming as is the case with most tangs.
