Well here is the situation. I had a 20G tank just sitting lonely in the attic, and a stand for it just hiding in the backroom. So I filled it up with saltwater and tomorrow after work I plan to get some dry sand and LR. Anywho, after it is done cycling (doing the shrimp method) What restrictions are there on live stock with a standard fluorescent fixture? (used to be a FW setup) Obviously I don't plan to put an coral in there, but what about other inverts (urchins, crabs, feather dusters, lockness monsters, etc) ? Not really sure what fish I plan on putting in there yet, just got the itch to setup another tank.
