Got new corals, Got new unknown creatures

[Royl14]

Hey just got new corals from 2 years working aquarium, lobophyllia and 25 heads of Zoa.
The lobophyllia came with massive brittle stars and some snail? I really don't know.
Flat worms started to show today aswell...
Please help me identify -
It's looks like he's eating some white string and pulling it.
And then put out 1 "leg" that look like a branch on picture.
And if you see from his left there a bit long worm / bug with stripes ...
I'm definitely concerned from the worms too...

Get those out of your tank and into a coral dip ASAP.

Um did you not dip them before introducing? Brittle stars are ok but flat worms?? Do you have flat worm stop on hand

Nope, that the problem I didn't.
I trusted the man cause I knew he has a food running tablet for couple if Years but yeah first mistake I will never do.
Actually it's one of my almost first corals so I'm not that familiar with the dip procedure of corals, only have 1 clown.
That creepy thing on the lobophyllia I assume is very bad according to your response?
I know flat worms are really bad and tomorrow I'll buy some stop for that ( any suggestions to what to buy?)

The snail on the coral looks like a vermitid which is a bad snail.

KZ flatworm stop
Pretty much the standard. Flatworms eat coral. Always dip coral from anyone.

I have a very good friend who I get ALL my corals from. I know his tank welll, and his maintenance, but I STILL dip what I get from him before it goes in my tank. Just not worth the risk. There are many different coral dips out there, but I use Tropic Marin Coral Clean

That string eating thing is a vermetid snail. The string is its way of catching food. A dip won't kill it.
Take the coral out, cut at the base with a pair of dykes. The base looks like a pile of poop. Just cut it, smash it, whatever. Quick tank water rinse in a container and back in the tank. Should take 2 minutes tops.

Word of caution, where there is one, there's probably more.

I would get those corals dipped and treated ASAP you do not want vermetids in your tank
