What type of seaslug/nudi is this?

[Holy handgrenade]

So i had some weird looking growth on a zoa frag plug and on my dry rock. Someone said it was colonial hydrozoa (Turritopsis dohrnii). I was going to remove it but i got tied up with work then got sick.... go figure. Well im looking at the spot now and see no sing of the grown but in its place some white seaslugs.

Should i remove them? They seem to have eaten the hyrozoa so they might be beneficial?

(First two pictures are the hyrozoa, other two are the slugs)

Kamden's Nudibranch Thread

So just a disclaimer I do not own a Nudibranch however I have done tons of research and have identified most of Nudibranchs and their food sourse The First Nudibranch i'm going over is Chromodoris Quadricolor, These Nudibranchs are an easier species to feed IMO, They feed on the Sponge...

Thanks my friend! It looks similar to the fringeback nudi mentioned in that thread. I think its kinda funny and amazing that these little guys came out of nowhere to eat up my hydrozoa problem

Are they? I dont have any montis in my tank so thats good. I have rics, zoas and some gorgs. Why would they have eaten hydrozoa then?

They do look very similar! Good side of this is they did do me a service. Im not planning on having montis in this tank so im sure they will die after all the hydrozoa is gone. Would be interesting to know what type they are and where they came from.
