Hello!

welcome!! good job on the research. believe me it will make your head spin. lol. I made the mistake on putting a yellow tang in my 55 gallon and it was too small. poor guy was really suffering after he grew a bit. got a flame angel in there that's really something else. funny personality and him and my foxface are inseparable. nice to watch. I'm planning in upgrading soon so don't think that a foxface is good for a smaller tank for much longer. this has been a great forum and I got most of my knowledge from here. hope you enjoy this hobby as much as the rest of us.

 

Only the smaller ones though, that stay around 3" (think Cherub). Any that are larger require bigger tanks IMO.
