My hair algae looks like this but alot more and the algae is growing on the free floating java moss that i have in the tank. I have to 2, 2.5 inch mollies that aren't touching it. What fish eat this exact algae that is in the picture not the stuff that grows on leaves that other people are talking about? Please only people that actually had this algae answer this question not people with second hand information because i don't want to waste money like i did with the mollies. My tank has the perfect chemical balace it just happened when i introduced water from my backyard pond. Yes i know, stupid mistake. The java moss was perfect before.
