I am new to saltwater aquariums and I want to get a decorator crab...

[ArchieFernandes]

I am a starter to saltwater aquariums and I have a 6 gallon tank and I want to get a decorator crab because I feel like I am not ready for a reef aquarium (mainly because of budget an size of tank) and I want to know if I can keep a decorator crab in a 6 gallon fish tank?

You can do corals in any size tank just get a good light and dose for coral who need extra supplements
