I want a fish that will strictly eat algae. And I don't want one that will get huge. I only have a 22 gallon COMMUNITY tank. So the fish shouldn't be aggressive. I was thinking of getting some CAE. What do you think?
If by strictly algae eating, you mean a fish that never needs any other food, then I'm not sure evolution has got that far. But if you want something that does a good job on the algae, supplemented by occasional other foods, then I would suggest either a bristlenose or (if the tank is mature) a small group of otos. For thread algae on plants and things, amano shrimps are good, but they will not scrape the green algae off your glass. CAEs eat less algae as they mature, they grow to a fair old size and they can get aggressive, particularly in small tanks.
Actually, ghost shrimp are scavengers and will clean up excess for but don't eat algae. The key to an algae eater is what type algae you have. Different fish & shrimp (amanos) will eat different types of algae but won't touch other types so it's hard to say that any particular one is perfect and take care of the particular algae problem you have. Here is a pretty good article on different types of algae and the types of fish that may eat each one.Would ghost shrimp work for threaded algae?
