I've had my frag tank set up for a few weeks now and am starting to notice some algae growth on some of the frags. The tank is only about 6-7in tall and I wanted to see if anyone had any good recommendations of a fish I could put in there to help with algae maintenance? Currently I have a 6-line wrasse, blue leg hermits, and some cerith snails. Would something like an algae blenny be a good choice?
