I acclimated four fish and put them in my tank. A firefish, a chalk bass, a dispar anthias and an orange spotted goby. The firefish was out and about in a day. The bass took about 3 days. The anthias took about 5 days and still just comes out for a few seconds at a time. I have not seen the goby since I put him in. I have no crabs, not even hermits. Any chance he is alive. It's been 10 days. The tank is an Aquapod 24 gallon with lots of places to hide in the rock.
