Is it necesary to put snails crabs and sertant shrimp. if so how many and which ones

 

[fishfreek]

necessary.

No.

snails will help clean your glass of algae, crabs will do the same for your rock. they will also help on any uneaten food. serpant stars can be used as sand sifters and some just plan like the looks of them.

 

[lordviporscorpi]

serpant stars are star fish right? and if so can i keep starfish in my tank if it has coral

 

[kribbz]

yes, but only reefsafe starfish as some are known to be non reefsafe.
