I don't know what to do . I have a small 15G tank that has 3 little clowns in it.....because it is a fairly new tank I am still trying to deal with algae. I added a 3-4 hermit crabs and several snails to help get raid of it, but the hermit crabs kept killing the snails (even though they already had a bunch of empty shells)......I went to my LFS for suggestions, and they sold me 2-3 large turbo snails and said they would be safe because they were bigger than the crabs.......... the crabs got to 1 of them but the others made..... on another trip, they suggested I add a sea urchin to my crew...... I did, but now the urchin killed the snails by wearing them as hats and/or the snails are not "cleaning", if they spend their time in a tour of the tank on top of the urchin . any suggestions on what I can add to my crew???
This seems like a lot of little creatures for 15g. The clowns will get bigger, so I would first suggest an upgrade! BUT are you only giving the turbos and hermits the algae in your tank? I will sometimes give hermits algae chips/wafers and I've never had a problem with them hurting the snails. You could also look into copepods. Ever since I added them to the tank (plus some fish eat these) I have never had an issue with algae with them in the tank.
