Pink and green sea cucumber, Pentacta anceps

[Reefyone]

Pink and green sea cucumber, Pentacta anceps - it won'ts open whole day and night after moving to another, likely very good, tank. After short acclimation in the first, more dangerous tank, it started feeding all the time. And now it just sits without feeding tentacles.

Your experiences or other info, please.

Maybe flow should be directed directly onto them, not just pass nearby?
Maybe they can't climb acrylic walls good enough?

No problem now: flow should be directly onto cucumber and add more food - ZooMax, ZooPlex, Cyclop-Eeze and other.

these cucumbers should be able to move around to where they want to be. most are detrital eaters and will pick through the sand.
