Yellow Nudibranch that bearly ever moves..

[arcanehacker]

I bought a yellow nudibranch few weeks back. Thing is on the first day I placed it in the tank, it crawled up a little onto the tank. Till now, its still at that position. It bearly moves. Moves only like few mm here and there once in a while. Also the occasional letting of tail sway in water. ..

Doesn't it eat or something? Or is it some filter feeder? I know it doesn't eat sponges coz it would have gone over to the sponge.

I tot so too but do sea cukes have tails like nudibranches?.. coz I've seen sea rabbits and the tail looks similiar...

only difference is that this 'thing' has many many suction thingy like those on a starfish...

oh.. ok... thanks everyone... Sea cukes are scavengers and eat algae right? Then why isn't mine moving at all? There isn't algae on my tank what?

That's a sea cucumber and I believe it's a filter feeder. It'll position itself high up on rocks or the glass wall and extend its tentacles to catch passing food particles.

Watch that it doesn't decide to climb up near a powerhead and become minced meat. It may release toxins enough to harm your livestock if you have a small tank.
