Glad I stopped by found this thread very handy due to old saying In the same Boat Waiting on the same sponge filter from amazon to put in sump for my QT have some rubble rock curing there also since I started my tank so some of that goes w/sponge filter. I just have one problem. ..haven't decided on the fish I want to add, three Banggai Cardinals, yellow head jawfish or a sandsifting goby......currently have 2 ocellaris clowns and a female black molly 3 hermits and about 20 or so assorted snails in a 55g. Looking for a fish that moves has a personality so I think the banggais might not be a good choice , do want to keep a docile tank but looking for that display fish.
