That's ridiculous. The "and" part is even more ridiculous.

In my 90 I have 1 black brittle starfish (the only large starfish with good long-term survival and safe for fish), 3 Ring Cowries, 4 Astraea snails, 1 Fighting Conch, 2 Peppermint shrimp.

Be aware that hermits will eat snails when they get hungry.
