:roll: Anyone know how many turbo snails and hermit crabs, sea sifting stars should be in a 75 gal. reef tank that has been established for 5 years. The guy I bought it from informed me that I may need some more crabs, snails...etc. Right now I have 5 turbos and approx. 15 blue leg hermits and one sea sifting starfish and 3 cleaner shrimps? Is this a low #? Please advise, any comments would help. Thanks again! KA
