Sea cucumber injuries, small "chunks" missing

[NeveroddoreveN]

I got a sand sifting sea cucumber a few days ago and it immediately did great, eating, pooping, super active, etc.

But overnight about three different ulcerations appeared, like it has white holes in the sea cucumbers body.

The only other inhabitants are a cleaner shrimp, some snails and a damsel. I do have some some pretty gnarly amphipods that swarm-attacked and killed an otherwise healthy maxima (that's an other discussion).

Have any of you seen anything like this?

I'd ask @Jay Hemdal. If that's a bite, it looks like a big one. Makes me think it's an injury instead or maybe an infection.

Many cucumbers are toxic, so few animals will bite them. This could be a bacterial infection. Be careful, as cucumbers can release their internal organs as they die, and that can prove toxic to other tank inhabitants.
