I have had my reef tank set up for 3 weeks now and finally the diatom bloom is gone, but now I have green hair algae. I am currently stocked with two clown fish and five hermit crabs. However, the hermit crabs are only staying on the left side of my 75 gal
but will not go to the other side where the green hair algae is. I only started with five hermit crabs in order to clean up the leftover food that my clowns didnt eat. Now im ready to add a few more crabs and a couple snails. How many more of hermits and snails should I add? I dont want to starve them once they quickly clean up. Also, I do not want huge snails because they will end up bulldozing the corals that I will add to the tank. Thanks in advance.
