I've got a bunch of aptasia growing in my sand bed and some kind of tube worm-like thing growing all over in my rocks. How could I get rid of them? I'm more worried about the aptasia. I was thinking about getting a Peppermint Shrimp but was worried about it having food after all the aptasisa are gone and space in my tank. I have a 32.5-gallon tank and I want a cleaner, fire, or coral-banded shrimp in it but wasn't sure if the peppermint shrimp wouldn't have enough space or would get bullied or something. Any thoughts? Thank you!
