How many inverts?

[TheOneWhoIsThere]

I am starting a 20gal cube reef planning on starting off with 1 or 2 corals, diffidently a blastomussa. I am planning on adding some clownish, some cardinals, and a watchman goby. What types of snails/crabs should I get and how many?

10 snails and 5 hermits

I have almost this many in my 40 gal. And have never really had any noticeable algae... I would say get half this amount and adjust accordingly if you see an increase in algae that they cannot handle.

I kind of regret my hermit crabs.. So many snails eaten. I would have gone with Mexican turbo snails, black foot trochus, and a few cerith snails if I were to redo it.

Maybe the hermits will be sumped eventually and I'll restock snails. We'll see!
