Anyone know what this is?

I found a stick like structure on my green candy cane coral
It’s had good growth and I’ve had it for a while
Does anyone know what the white stick on the skeleton might be
Thanks

Looks like possible vermetid snails. If so, I would remove as they can spread and annoy corals.

Second, vermetid. If you can pull the coral, scrap off and glue over to kill. They are a pain.

Sponges, unsure of name but they grow similar, they smother my candy cane and GSP

Ok thanks I’ll try to remove them soon

I think bumblebee snails chow those things up nice as well

Yep, vermetid snails ... the tiny variety. Shouldn't cause any problem for the corals.

As for bumble snails, a few folks have had some luck with them eating vermetids, others have not. And they are carnivorous ... so bear in mind they may pose a threat to other CUC snails in your tank as well, not just the vermetids.

I still think sponges, from pictures they are very white in colour. vermited snails are generally brown or red, with a deep colour calculus shell.
Either way , if possible just remove from aquarium, 2 containers of your aquarium water , scrub with a toothbrush (best is a baby toothbrush/ very soft) in first container, rinse in 2nd container and place back in aquriam
