Just saw this on the front glass I think maybe a nudibranch ???

Yes it is.
Not a good guy.

Agree with Salty, get it out of there whenever you get the chance.

There's a decent chance that it will have laid eggs on or near its favorite flavor of coral. The most common varieties in the hobby these days seem to prefer snacking on zoanthids or Montipora, so keep an eye on those corals.

Thank you, from what I saw when I was looking at nudis their eggs are a spiral type of thing ? That tank i found it in is all softies ,zoo’s leather etc so I’m guessing they’ll be in the zoo’s. Wonderful!

 

[Mick51]

So after pulling about a dozen or so more off my zoo’s I’m wondering how many
I can’t see is there a dip or maybe freshwater dip ? Any suggestions don’t need this getting out of hand

I've read good things about both RO/DI / iodine and Coral-RX dips. In terms of reef-safe treatments, your best bet might be a Halichoeres wrasse, such as a yellow "coris". I would expect any chemical that kills nudibranchs to have a negative effect on any snails in your cleanup crew.

Best solution might be to isolate _all_ zoanthids to a QT, and dip frequently until nudibranchs no longer appear - and then cross your fingers.
