Zoa Pest ID

Arcticwolf · Mar 27, 2020

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

Hi,

How long have you had them? Sounds like a long time. Any new additions. My guess would be Nudibranch, but not 100% from the pic doesn’t look like it

I've had my zoas for a long time, but added 2 frags recently from someone who told me he couldn't keep zoas. I wondered why because they seem easy for me. They went in around 3 weeks ago. I couldn't break one of the frags off the plug because it had encrusted around 3 sides, so I'm guessing something was hiding under it. I dipped but clearly whatever these are made it in. I thought maybe nudis too but they have no 'tufts.' I've tried flatworm exit and flatworm stop and they seem to keep spreading. So frustrating!
