I have been reading through this site for some time now, and hopefully I am on the right track to successfully keeping a ceph. About four months ago I gave in and started a tank. Reading through the forums such as this have been a big help, but I would like to know if anyone has suggestions about my setup before getting a ceph. I am open to an octo or a cuttle; it mostly depends on the best match for my setup and availability. I have easy access to hermit crabs and snails for feeding. Thank you all for the wealth of information on TONMO! The setup: 90g (acrylic) ~100lbs live rock 3" aragonite substrate Canister filter Protein skimmer Fluorescent lighting -- 1 emerald crab 3 hermit crabs 2 snails -- SG 1.023 Ammonia, Nitrite 0 Nitrate < .5 PH 8.3 I still need to upgrade the protein skimmer and seal off a couple openings.
