I just noticed these growing in my tank last night and want to figure out what they are. I think the red ones are coral polyps. The others look like rocks growing up with opaque tentacles coming out of them.

Thanks in advance!!!

the second ones are spaghetti worms.

Actually they look like vermetid snails... The things that look like a tube of rocks with a thin worm coming out.

Vermetid snails expel a weblike thing, spaghetti worms have translucent feeding probes like those in the pictures.

To me, the hitch hiker in the 2nd pic doesn't look like a worm/snail, but more like a pest anemone. It seems it has a little baby next to it. I could be wrong.

The second pic looks like it was recovered from WWII
