Cucumber on Glass?

[Reef Keeper]

Hey everybody,

I have had a Tiger Tail Sea Cucumber for about a year. It has spent most of it's life living under the rocks. However, this morning I noticed it up on the glass towards the top of the aquarium. He is steadily moving across the upper portion of the glass with his tentacles out.

Is this an unusual behavior? Should I be worried?

Thanks for you help in advance.

I caught my black cuke doing this a couple of times. No ill effects. As long as they don't find a CL or powerhead intake you should be fine.

mine goes up the glass once in a while also.

Thanks for the reassurance, I hate to be unsure when it comes to a cucumber. I've read too much about the horrors of when cucs die.
