So I've had my zoas explode in growth and they were climbing my back wall nicely when I noticed them starting to close up. I gave it a couple of days before investigating and used a target feeder to blow them off. I can see little bright pink spots that move like flatworms but they don't look like flatworms. I managed to get one with the target feeder and it's body looks like a teardrop. They almost resemble a single zoa skirt 'lash.' I assume their color means they have been eating my zoas but what are they and how can I get rid of them? My zoas aren't dippable as they have grown over all my rock and up the glass
