What is a good clean up crew for a 90 gallon reef tank? So far I have 6 astrea snails and I figured adding a couple of dwarf hermits (2-3) and a starfish? To tell you the truth in my tanks I have never really had to worry about a clean up crew but I am looking for a long term success "crew" to help me out. So if anyone has any suggestions that would be amazing. Thanks a million and happy fish keeping!
