Ok I have a 24 g tank. I have 12 turbo snail 4 hermit crabs a crab I never see. I have a coral banded shrimp and a brittle star and a sand sifting star fish which I am probably taking back. Oh and a blennie and 2 perc clown fish. My question is I order some Nassius sp? snails and they come in a 20 pack. Is that to many to add? Thank yo for the advise.
