I have looked alot of places at clean-up crews. Everyone is different. Everyone has a different opinoin on what you need and what works. I looked at one and they said mexican turbo snails will die due to the temp of the water in reef tanks. So why are they included? Alot of people say hermits are bad but they are included also. Where can i get a Clean-up crew that works. TRhat what I want? Anyone ?
