I'm looking to add a clam to my tank in the near future, well maybe not too near but after my tank has completely stabalized and is established. I was wondering what kind of clam I would be able to keep in my 24G for about a year and a half. I say a year and a half because I'm planning on upgrading to a 80 gallon within that time. I'm trying to plan out what corals I would be able to keep with that clam as well as what fish I would be able to keep. I've had my tank for about 2 months now and currently I have 2 clown fish, a clean up crew, a torch coral, hammer coral, frogspawn corals, and a zoa colony. I would like to add more soft coral and maybe a few more zoa colonies. Any suggestions?
