need help ASAP identifying this worm

[MontanaDolphin]

Should I keep it out or put it back in? Is it a medusa/spaghetti worm? Or something else? If it's ok to put back in, I need to know ASAP before it dies out of the tank in the dish. THANK YOU.

I'd say long one is a bristle work great for CUC IMHO. The other is a Spaghetti worm, I think it's OK, Madusa needs to get out. here are some links with pictures and others will jump in to correct me if needed. Good luck!

I'm no ID expert but based on the attached article I don't think it is a Medusa. Very cool article about them though.

Great find, here is a text from that document:

"The tropical worm is capable of inflicting permanent numbness on humans with its sting.

Matt Slater, the aquarium's curator, said: 'Something was guzzling our reef but we had no idea what, we also found an injured Tang Fish so we laid traps but they got ripped apart in the night.

'That worm must have obliterated the traps. The bait was full of hooks which he must have just digested."

The poor thing "Swallowed" the hooks LOL

Medusa, is a bad word, as it is used for spaghetti worms, some feather dusters and sea cucumbers. It is a spaghetti worm.
