i have had a 55gal tank set up for over a year now. problem is i don't have much in it. truth be told it's only now starting to look cycled. it's a corner tank, tall. i have only one surviving green chromis, a fire fish, lawn mower blenny, and a yellow tang that will either go in my 150 gal fo tank or back to the fish store. i have a few corals, i will be getting more at a later date. i have 20 hermit crabs, 10 nassarius snails, and a 1 1/2 inch red fromia sea star. what should i get next? i'm thinking 20 more hermits, and maybe 10 more nassarius snails. i want to get a good clean up crew befor adding anything else. once that is done what fish would be good additions? all input is greatly appreciated.
