Rouge Nudibranches

[webbl19]

Have no clue where these guys came from. Havent had anything new in months. However i spotted one on the glass today, lost it, when searching for him again. I found these 2 hanging out by some zoas. Are these zoa eating nudi's?

They look like zoanthid eating nudibranchs; remove for sure. Possible they've been in there for a while. Assume that they're breeding and looks for eggs in your colonies:

Awesome. Thanks.

Will the flatworm exit hurt any other good critters in the tank?

In higher concentrations, nassarius snails will kick the bucket. Cerith snails seem to tolerate the treatment. If you have flatworms you may want to be careful.

You can also hit them with actinic light and they will express the color of whatever zoa they've been eating and you can focus your eradication methods on that particular colony/colonies. Best to probably treat them all, however.

Up to 6 now!

Any chance these could be the cause of my acans unhappiness? I have 6 frags of acans. Were all doing super good one of them was spreading and then the last month or 2 they have been sucked in. Do these nudis eat acans by chance?

Sorry got some stuff floating around from turkey basting lol.

Nudibranchs tend to be obligate predators and only go after 1 thing. They look like zoa eating nudibranchs unless Acans are eating the nudibranchs I can't see a reason to cause them issues and that's a rather far-fetched idea.

I didn't think so, but thought id check. Only thing left is lights other than fish. Been up, been down. Nothing seems to make them happy these days. I almost think its my coral beauty pecking at them. He goes around pecking on everything. Havent seen him do it though and ive been watching. SMH
