So i was told that getting a Blue Hippo Tang might help with my hair algae problem... I have a side of the tank that i guess the flow isnt getting to or something and hair algae grows and grows and grows. Ive been pulling it off with my hand trying to figure out what to do but am tired of that. Is this true that a tang would eat that stuff? Ive been planning on getting a Blue Hippo Tang anyways and would get a small one since i only have a 30g (about to setup my 55g so it wont stay in the 30) but wanted to ask the audience. This a lie? or just a possibility? or fact?
