It's a nudibranch of the genus Thuridilla. Looks like a Thuridilla decorata, but they only come from the Red Sea. I would say yours is a Thuridilla gracilis. 99% of nudibranchs you don't want in your tank. They have very specific diets and I'm not familiar with what this one eats. They rarely live a year old and they breed like rabbits.
Oh goodness. Another creature for the watch list. I need to setup cameras to monitor how big these eunice and fireworms I see sprouting up are getting.
I saw another one the other week that may be a nudi also a lame picture but its the little thing on the glass.
Hello guys I was just wondering. This morning I woke up and there was this weird slug thing in my fish tank, it has no she'll but it does have some weird red/pink thing on its back. I have 2 turbo snails could it possibly a baby snail growing a shell? Or is it some type of parasite and I should remove immediately?
No idea what this thing is? Found it on a rock I have had going on five or six years. This rock is now in qt with my acros getting dipped once a week and it is evidently not affected?
Trying to upload from my phone. If it doesn't work, I will post photo at lunch.
This started growing on my L.R. a few weeks ago and now another one is beginning to form beside it and it continues to get larger every day. My guess would be some kind of tube dwelling worm but I have no clue.
I am also curious about this little guy. It looks like another that was posted earlier but the color and lack of any 'shell' is throwing me off. Just want to make sure its welcome.
...ok, just one more for today... (these critters fascinate me). This guy has anemone like tentacles with balls on the ends and has been popping up in random shaded parts of my tank.

Looks like an abalone to me usually has a small tiny shell but it can sometimes fall off its a snail that does a great job cleaning up algea and detrius if that is what it is
