Hi, I had some nudis in a zoa colony. Dipped it In Melafix by API every 3 days and picked out the bigger ones with tweezers. I haven't seen a nudi since and I'll probably keep dipping every 3 days a couple more weeks in case any new ones hatch.
Not sure what that is but a few of them shouldnt be able to make a big dent in a pod population if they do decide to eat them. Let me know when you identify it and ill have better info!
