I noticed a couple of these in my tank tonight, and have no real idea what they might be. They appear to be some sort of anemone, but I don't think they are aiptasia. They have a pink base, white tips, and small green spots in the disk. They do not extend out from the rock, but are rather flat against it. They are about the size of a dime. Any ideas? Hopefully they are not a pest as i have maybe three or four of them that i know of.

anemone
I remember there was a post about these a few years ago....I can't remember the exact name, but it was definitely a type of anenome, and people seemed pretty excited about having them in their tanks, so I doubt it's considered a pest. I wish I could remember the name.... :?

in case anyone else wants info, I just found some.
Pseudocorynactis spp. are like Corynactis but are much larger (to about six inches (15 cm) diameter, and usually not colonial. They also reproduce by fission, but it is unusual to find more than about six clones together as a group. The so-called orange ball anemones that can be observed on coral reefs at night are Pseudocorynactis spp. The column varies in color from cryptic shades of brown to orange, red and magenta. The tips of the tentacles are commonly bright orange, but they can also be white. These tentacle tips are extremely sticky, like flypaper, due to the presence of powerful nematocysts. This fact makes the larger species from the Indo Pacific region unsuitable for aquariums housing fishes, which they readily capture. They also can catch mobile invertebrates such as shrimps and snails, and sometimes "attack" sessile invertebrates growing on adjacent rocks, enveloping them in the gastric cavity through a widely opened mouth. Pseudocorynactis spp. can be fed daily, but only require twice weekly feeding to keep them healthy. If they are not fed frequently enough, they shrink. There is a marked behavioral difference between the common Caribbean and Indo-Pacific species.

I'm not sure if I'd want one in my tank.
I figure if it gets to big, I'll just treat it like aiptasia. But as long as it behaves itself I will definitely enjoy having it. Luckily, its in a spot in my tank that is not really visited by my shrimp or fish.

They get as big as a dime. I have hundreds of them throughout my system. They shy away from direct light but do not exactly stay in the shade.
You can see them all across this rock.
