Dwarf Lion in a 20?

[kev]

Would it be alright to have 1 dwarf lion in a 20 gal? All by itself... ?

Well thats good, lionfish are one of my favorite fish. I have a 10gal that im going to make a refrigium with, that should help with the water quality a bit... I was thinkin it would be alright but thought I would get me a few more opinions!

ill second that thought, as long as it is a dwarf we are refering to and not the possibility of a larger lion, the 30 woould definitley be better,, but .... especially if yo are using a sump too, that would help with the lion(they need most of the space for bioload, mor than activity), they are messy
