My friend has 2.5-3 in. red ear sliders. They are rather....aggressive.....and overly hyper....to put it nicely. o_o; Well she has an algae problem in her tank right now and she doesn't really want gravel. She does have a filter. Does anyone know of an algae eating fish/creature that won't get its appendages ripped from its body? It is a 10 gallon tank. Thank you.
