I had about a month of brown algae. It has finally almost all cleared up. Tank has been going for 8 weeks now. Have 2 clowns and a damsel. My question is i have 5 snails and 3 hermit crabs and since the algae is about gone what do they eat? I would guess there will still be some types of algae they can eat but do i need to think about getting food for them? When do you think i could start adding a coral or two? Have biocube 29. All levels are at 0. PH is maybe 8.2.
