I`m a little concerned about the CC star. One of the things that`s needed in this hobby is lot`s of research. I dont think you`ve done enough on this project. According to Liveaquaria they say " A large aquarium with open access to a mature sand bed several inches in depth best recreates the preferred habitat of the Chocolate Chip Sea Star." I personally dont think your star will live long in that tank. They dont eat brine. And even if they did brine has little or no nutritional value. Liveaquaria also says "
In the aquarium, the diet the Chocolate Chip Sea Star can consist of chopped clams, shrimp, and squid." It is a carnivore and needs meaty items. Here is the link to all the info I gave you. I would rethink the project if it was me.
