As most of you know I have a FOWLR tank, so I know very little about corals (except the few tidbits I pick up from you experts :D ).\n\nI'm considering doing a pico vase w/ just a dsb, live rock, and coral. Do all corals require food? Like, mysis, or cyclopeeze or something. Or are there corals that are strictly photosynthetic? I guess cuz they're technically animals, they all require some sort of food, right?
