I have been reading back for an hour now and have seen it said to keep cuttlebone in the tank. If I have a UVB bulb (that is not out of date), do I need extra calcium?
I tried this once, but being a rookie, we finally threw it away. When I buy one, do I knock off or break the thin layer from the plastic part and let it float? It seems like chalk,,,can I expect it to fall apart and disappear before he eats it?
Thanks,
Christi
