Could these be Acro eating nudibranchs?

[JCOLE]

I have been going through some issues with my tank by doing to much at one time with Vibrant, chemiclean, and Fluconazole. The result has caused a couple frags to die.

I put some berghia nudibranch in my frag tank about 6 months ago for Aiptasia. Didnt lose any Aiptasia and ended up sucking everything out of the frag tank. Haven't seen the Berghias since.

I lost a frag and pulled it out and noticed what appeared to be little baby berghia nudibranch under the plug. I just lost another high dollar frag and noticed the nudibranch on that one. I just snapped these pictures. Do these appear to be berghia or something much worse?

Keep an eye on the bases and look for bite marks.

Are there Acro eating nudibranch? After doing some searching I am finding conflicting results. A lot are saying that they are montipora eating or different nudibranch and they are eating the dying coral from other reasons.

I’ve personally never seen any/experience, but I have read threads. Bite marks will be the indicator

they look like montipora ones. Some claim they would munch on acros

This is what you’re looking for and also scan daily for eggs

They seem to congregate around the bases of these frags. I dont see them on any other corals in the frag tank. The frag tank is all Acros except for a couple digi's and a cap.

They do look identical to the Berghias but just a lot smaller. I don't have any Aiptasia in the tank so if they are Berghias then you would think they would starve.

Those are Berghia's. Their mother probably laid the egg ribbon on the bottom of the frag plug, It took my Berghia's at least a month to starve after they cleared out all of the aiptasia. And they do tend to congregate in groups since they are pack hunters.
