So I got a lunar wrasse awhile back an it ate all my snail. I have a black urchins that still lives so if I go a few different types of urchins would he eat them. I need a new CUC.
Yes. A lunare wrasse will eat urchins. And shrimp, hermit crabs, other crabs, guppies (fun), etc. I think my old lunare wrasse would have eaten my magnet scraper if it had fallen from the glass.
