CUC for 24g cube reef?

[PoseidonSquirrel]

I have a 24g cube that currently has:
- 2 clown fish
- 1 banggai cardinal
- 5 hermit crabs
- 1 conch
- 2 nassarius snails

What else should I add for CUC? Shrimp, more snails? I deal with hair algae 2 years in and that’s about it.

Urchins and margaritas can do great work on algae. Emerald crabs too
