I've got some aiptasia popping up and have heard that Matted Filefish will eat them. My question is will they also eat my corals? Has anyone heard or have experience with these fish. I've had a CBB but it got a bad scratch on it's eye and didn't recover so I'm lookin for a different fish that can do the job...maybe a crab would be nice, but I doubt there is one that will do that. Any info is great. Thanks
