Algae Eaters?

What type of algae are you having issues with the most? Many algae eaters only eat a specific type of algae (or types) and not every kind, so narrowing it down can help us with some recommendations.

It would really help if you could tell us what kind of algae you are having an issue with. There are a lot of algae eaters for saltwater tanks but as said above, many only eat a certain kind of algae so just getting any may not help with your problem if they may not eat the algae, you have an issue with.

Hermit crabs I know do eat all kinds of algae but that would depend on if you were able to have those in your tank.
