Hello all as I stated before in some of my other post, I have received an establish biocube 14g which currently houses two small clowns a turbo snail and some live rock. What I want to know is what should I get for a clean up crew. I would like to get things that my two little sons would love to watch. Also what do you think I should get for cleaner shrimp. I'm new to the salt world and really don't have any knowledge on what to purchase. If you could also tell me where the best place to buy them.
