Me and my husband just started a 55 gallon saltwater tank. We have everything set up except our fish are being delivered friday. We got 4 damsels. a yellow, javenese, green, and 3 strip. Now Im concerned about my coral if they will hurt themselves. Another thing is my father in law gave up fake plants for the tank, he told me not to use live plants becuase of snails. I want real plants though. Any suggestions!
