Elysia ?

[ginpang]

I haven't purchased or added anything in the tank since I bought a rock and two shrimps in October....and besides chitons popping up everywhere . Everything else has been normal.
Now these little bright orange slugs have appeared out of nowhere.
They're like maybe 3 mm. I've been trying to get a decent picture to get an ID. Turns out to be pretty difficult.

This is all I have for now ... To me it looks like an Elysia obtusa without the white dots!? Any ideas ???

It doesn't have a shell. Structurally looks like an Elysia or an aplysia .

Looks like one to me. I had one that came on a coral that was red.

Have you tried SeaSlug Forum? I don't know if Bill is around anymore, but if you go to the Participants page you'll find a list of contact info for approved SeaSlug specialists.

So the last time I saw them was when I took the pictures4 weeks ago. I thought they had been maybe scraped of a window along with algae or coralline ... But no they are live and kicking though they seem to have really slow growth or stay fairly small.
Because they don't seem to have changed much in a month.
And when I google Elysia obtusa I get pictures of specimen apparently from 10 to 15 mm which is about 3x the size mine are.
Starting to wonder whether they are another species!?

I have those too, I had a bloom of about 30, but I'm down to about 4, I recently read that they eat caulerpa, so I'm going to try find some for them. I've only got chaetorpha. They apparently suck the juices out of macro algae so they don't eat it, like to death, but I loved doing a daily sea slug count. I keep soft corals and have rarely seen them on let alone bothering anything.

Cool did they ever grow bigger?
