20g reef clean up crew?

[Evan West]

So i am setting up a 20g reef tank as my first tank and the stock is as follows:

2*Clown fish
1*Firefish
1*Orange stripe prawn goby
1*cleaner shrimp
1*porcelain crab

Do you think a clean up crew is appropriate? I was considering a scarlet hermit crab and a snail or 2, what do you guys think?
