Spionid worms I believe.

Vermetid snails. Spelling may be wrong. Had these in my tank a while ago. Too many nutrients. I cut back my feeding to once a day and they are almost all gone.

Agree, vermetid snails. They send out sweeper tentacles that sting close by corals. Super glue them. You can try breaking off, but they typically come right back.

Has anything ever come out of the tubes? A Vermetid snail will send out a slimy net at feeding time, while a Spionid worm will just look like two fine hairs protruding from the tube. Also, a Vermetid snail will usually have a coil at the base of the tube while a Spionid worm will not.

Does the net look like cobwebs? I've seen that before... I've had some corals die off and wondering if they might be the cause ?

Yeah, they look similar to cobwebs. The links below have some pictures of both Vermetid snails and Spionid worms for reference, but you'll have to click on the Photos icon to access them.

Hi. I have these in my tank and then seem to be growing. I only feed them over other day. Any other solution?

Bumble bee snails did the trick for me
