My list of stocking for the 200 gallon I'm setting up is going to be half utilitarian. I always like things that serve a purpose. I'm going to try a trio of molly miller blennies in that tank. I hear they can group up and even though they are ugly, they apparently eat aiptasia. Also was planning on a convict tang, they are cheap and supposedly fastidious about cleaning algae. No one really seems to get them for some reason.32 is tough, that doliatus rabbitfish loved it.
