I am having the same problem right now. I watch my Zoa's very carefully everyday and as soon as I see my Zoa's closing up unexpectedly you can be sure there is a nudibranch close by. I take a suction such as a turkey baster and gently blow water on the Zoa's so they close up. Do not agitate them too hard because you might blow the nudibranch off. Once the Zoa's are closed up look for the nudibranch and then use your suction to remove the culprit. It's a good idea to turn off your water flow and powerheads before you do this because if you suck up the Nudibranch and it falls out of your turkey baster before get it out of the water than the current sends it flying and you eventually find it later after you loose another colony of Zoa's. This has happened to me. I just sucked off another 2 Nudi's this evening.
