I have had my tank since september 2011. I have just started seeing hair algae showing up in my tank. I want to get it under control before it turns into a nightmare. I have heard that sally lightfoot crabs, black mollies, and turbos do a good job but idk what one to get. I heard lightfoot crabs get mean (but thats what I heard about emerald crabs and mine is well behaved.) Than I heard that someone got a few black mollies and within 30 days their hair algae was gone. I had 2 turbo snails from when I first got my tank and they were always eating algae...till they both died. They cost $4 each turbo snail and I think thats a rip off. Advice please?
