Chocolate chip star will eat corals, crabs and snails. The blue hippo will out grow an 80g.
I would look for reasons you are getting cyno. Nothing will eat it and stiring is temporary. Are you over feeding? Is the skimmer big enough and set ok? You could probably use more flow. Look at SIEO super pumps.
Otherwise looks like a good start. As a personal prefrence I would make 2-3 rock stacks instead of 1 long, short row. Thats just an opinion, do it however you like it best.
