Hey everyone, I have a 29 gallon tank I'm starting up to house bubble shell sea slugs (Micromelo undata and Hydatina amplustre). It has a 6 inch sand bed with some turtle grass and a piece of live rock. I plan on getting a couple more pieces of live rock and some sps frags and zoanthid polyps as well as the bubble shells as soon as my cirratulid worm population is ready to be grazed on (cirratulids are the exclusive food for these bubble shells). Basically, there are no fish or crustaceans in this tank (except amphipods) and it has a huge HOB Reef Octopus skimmer. I'm just curious if this is an acceptable enclosure for 1-2 Sepia bandensis cuttles. Also, would the cuttles bother Tridacnid clams?
