6-line wrasse *help* which tank should he go back into

[zum14]

Mines been in an open topped tank for a few months and so far ok. I need to get that fancy mesh though, I lost a firefish to carpet surfing. I would be worried about the other wrasse as well. My longnose hawk recently suffered a front fin injury and it was touch and go for a bit. Looks like hes going to pull through but im almost positive it was my 6 line that caused it. Ive watched them go at it before. I like him but am starting to regret putting him in my reef tank. Seems like hes more for a slightly aggressive tank where everyone watches there backs. Pretty much all cases result in terror with these guys. Is it a viewable refugium? Maybe a good home for him down there? Lots to pick at and will be happy if he has a couple rocks to zoom around and sleep in. Could be an issue if its 24hr lighting though. hmmm. Thats a toughie.
