Margarita or nerite snails, 1 brittle star, a good algae eating bleeny and good flow throughout. The blenny and star could both be skipped if needed. I only have both of the listed types of snails, a few left over hermits, and alow my pods to clean up whatever may be left. I only feed whatever my tangs, wrasses, and clowns can eat. My pods are over taking the tank at night so nothing is going to waste here.
