I found these growing on my LR. They look like some kind of anemone. Any ideas? Sorry for the poor quality, had to take them with my phone.

Also, any idea what kind of worm this is? It's in a 10 gallon tank to give a reference to size.

the top left circle in the first pic looks like a blue or green ricordia mushroom. They are good and very cool when grown. The other circles in the first pic look kinda like some sort of jellyfish, but they are hard to see so that might be wrong. The last pic is a ginormous bristleworm.

In the top picture, the mushroom looking one looked like the other 2, but eventually "tightened" up, instead of being long and stretched out like the others. It's hard to see, but they are clear tentacles with white tips.

The first pic, the one on the left looks like a small ricordea mushroom, but it is possibly a pseudocorynactis/corynactis. the right are a pseudocorynactis or corynactis. They are related to shrooms and are good to have.

The last is a Carribean bristleworm and it is predatory.

the top pics are ball anemones. they are kinda like aptasia, a pest anemone. i have them in my tank. i left them in, but they are spreading all over the rock. joes juice will take care of them if needed.

the second pic is a large bristle worm. i forgot what exactly that one is called. i would leave it out if it since its so big.

As anemonebuff said, the bottom pics are a Pseudocorynactis sp., a corallimorph (mushroom, basically). The second is an Amphinomid polychaete (bristleworm). can you get a closer shot of the head? There are some distinguishing characteristics between "good" and "bad" bristleworms that are found near the "head." I doubt it is a 'bad' one, though. Most, even large examples are perfectly harmless and even beneficial, with a few exceptions.

Yep, pseudocorynactis and an unidentified polychaete (need a pic of the head/"face" and how many "antennae" it has to help identify it).
