I completely agree with spanko. Here's my corallimorph...
They fall into the (nocturnal) mushroom family.

I guess I never noticed how much they look like hydroids, lol. That's kinda cool.

Quote from Juliqan Sprung:
Pseudocorynactis
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.
The Caribbean species, Pseudocorynactis caribbaeorum mainly opens its tentacles at night, and closes rapidly when it senses light. The Indo-Pacific species remains open both day and night, and is not sensitive to light. The presence of food smells (dissolved amino acids) in the water stimulates either species to open up and extend the tentacles, and the caribbean species can be trained to open in the light by feeding it during daylight hours. The mechanism for its apparent memory is not known.
Assuming that they are safe may in fact be a mistake. I found about six of them the other night.

I think if I ever see one that's got a diameter of 6 inches, I'd be more concerned, but the ones I had never got bigger than a nickel and I had them for a long time. Nor have I ever had one unexplained death, (except my neon, but rumor has it they only live 2 years in captivity anyway) and I found his body uneaten.
I think at this tiny size the worst we can expect from them is eating a few amphipods.
