new to SW. what do i need to look out for with these?

crap. i really wanted to get a dwarf lion too.

but that pretty much just rules out alot of other fish that i also want to get dammit.

 

^^+1 such is the story in this hobby when you want to do it right. You have to make those choices in terms of what you really want to keep or go with multiple tanks so you can keep most of what you want - unfortunately, you'll still even then have to make choices

I hope this doesn't upset people but I kept a dwarf fuzzy lion one time and it really was not a very interesting fish in terms of its swim habits - it usually hung out under overhangs and remained relatively still most of the time - they are very cute but I prefer more active fish that are out and about with active swim patterns.
