So I have 4 Mexican red leg hermit crabs and one banded trochus snail on my CUC. I just got a diatom bloom yesterday and it is quickly spreading. My question is...will the hermit's eat the diatom? how about the snail? Do I need to supplement the hermits food? I dont have any fish yet so I am worried that the crabs wont have anything to each with no leftover food sinking to the bottom. If so, what is the best food for them? one last question, What other additions to my CUC should I add. Its a 30 gallon tank.
