A friend of mine was importing corals years back and came across this hitchhiking "anemone." I jumped at the chance to keep one in my own aquarium for a while and I thought it'd be fun to quickly share some of the experience here, since it's a non-photosynthetic coral (corallimorph, technically) that's a bit different than most.

The good
- it looks like an anemone, but is much hardier
- it's non-photosynthetic, so lighting is irrelevant (this particular coral showed no sensitivity to intense light)
- unlike most non-photosynthetic corals, Pseudocorynactis does not rely on constant or tediously frequent feedings
The bad

- See above! They're non-photosynthetic and don't require constant feeding… which means they rely on big meals whenever they can get them…which means they are very, very adept at catching prey with potent nematocysts (check out the balls on the end of the tentacles).
You mean to tell me that the itty bitty cornyactis anemones that we have all over our tanks can get that big????????
