Just started my 14g biocube. It's been a month. I put 15lbs live rock and 18lbs live sand. I just put 8 tiny blue legged hermits in, 2 white legged hermits, 2 Scarlett hermits, 2 emerald crabs, 2 peppermint shrimp, 2 serpent starfish and some snails. Hoping I didn't go overboard. What can I feed...
