My clean-up crew, your thoughts

Hi all,

So this is my current cleanup crew for my 300ltr tank.

I got these guys yesterday and want to know if you think I should add anything else, or have more of something, or even if you feel I have made the wrong choice.



2 cleaner shrimp

2 peppermint shrimp

4 snails

4 hermit crabs (red legged)

1 emerald crab

1 other crab I can remember the name, it's white with brownish spots, it has claws but also two arms with spoon like hands that it uses to catch food. Also loves to perch itself on coral.



Anyways what's your thoughts?
