Sea cucumber predators?

[jpnegrete14]

I’ve read conflicting things so I’m curious about people’s actual experience on here. I want to add a sea cucumber to my 45gal cube for the purpose of helping maintain a clean sand bed. I am worried about crabs or perhaps even some fish trying to turn the cucumber into dinner TIA

I have tiger tail cucumbers, the only thing on your list I ever saw have a go at one is the blenny, if a cucumber was in it's fav spot it would bite it to try and get it to move, not try to kill it.

Thank you! I’ve also considered a diamond goby which I love and they’ve always done such a great job cleaning the sand in my other tanks but I’m worried about the yellow watchman goby not getting along with a diamond goby.

@najer quick question. So with everything we just discussed. Would I be able to keep tongan nassarious snails or will my crabs kill them all eventually? I’d like to get like 10 of them

The only thing I ever saw go for a nassa was a 3 inch yellow wrasse, grabbed the "snorkel" as food, dropped it straight away.
