View Full Version : i did a bad thing

well, i have broken a personal rule and went out and bought an organism--a sea pen--on a whim. i knew about the poor survival record of these critters, but i had also heard that the kind that i got (a <em>Cavernulina</em> sp.) are somewhat easier to keep. they are supposedly more photosynthetic than other sea pens. this one had been in the store for a couple of months with no special care and looked fabulous this afternoon when i made my purchase.

so, after you finish scolding me, can you please provide any suggestions that you might have on sea pen care?

I would figure most need a really deep sand bed.

From Eric Borneman's Aquarium Corals:
... primarily nocturnal filter-feeding specialists. They will capture small particles of detrius stirred up from the substrate and should be given regular feedings of zooplankton-like fare (enriched brine shrimp and other high-protein marine rations of small particle size). They tend to move around in the soft bottom and may even occasionally "float" out of the substrate into trouble. ...

yes i saw that thing in Borneman's book. he doesn't say too much about them. the animal is actually looking real good today. i might try to post a picture.

Here's (http://reefkeeping.com/issues/2005-08/rs/feature/index.php) some good reading about sea pens.
