Another stumper, at least for me.
I first discovered this critter approximately 5 weeks ago. It is residing on the back glass of the tank, behind EVERYTHING. It is actually very difficult to see, it's a wierd shot through the cave under my large frogspawn. I actually probably never would have seen it but for the fact that it is white, and as a diver, that is one of the colors I am trained to look for when spotting critters.
So one wierd thing is that it hasn't moved much, if any, in those five weeks.
It's in a spot that is early impossible to access without a complete break down of the tank. I mean it is WAY back there. So the first time I saw it I was like... "WTF?" but I had to get back to the hospital, so theere was no time to investigate. I expected I would probably not see it again for some time.
My first guess was some sort of nudibranch (a dorid, specifically) but the lack of movement makes me question that guess. A dorid moves around to eat. This dude hasn't moved. So, I have to lean more in the direction of some kind of sea cucumber or something similar that filter feeds, and the appendages at the bottom support that theory.
Anyhow, here's the photo I took tonight. Not great, but decent. I would love to know what everyone thinks.
What is this invertebrate?
