From what understand they are quite usually doomed to starvation in home aquaria. i am not saying no one can do it. I would rather buy an animal that is easier to take care of and see flourish in my care.

I don't know any scientific information, but....I had one for a while.

No direct feeding necessary - gets it energy or food from the light. Must be placed in sand. Will burrow into the sand at night and completely disappear, when light comes out/on will grow and emerge from the sand, it does expand quite a bit. Grows and shrinks itself day/night. Also has many beautiful arms with flower-like ends that come out of the stalk. Don't handle or move it too much, I think that is what killed mine. Like to get another but only seen really, really large ones. Not harmful to anything but other corals may injure or kill it.

I just busted out my 'marine invertebrates' book by Shimek... In it it states that they need at the very least 8 inches of substrate and in reality more like 12-24 for full healthiness. They need the substrate to deflate and hide into and will inflate to catch food. it also states most pens are from deeper waters and would be better off in a dimly lit tank. They eat tiny particulate foods.

I guess I might have been a little off. Never direct fed mine and I only have a SSB but it still seemed happy and healthy. Maybe moving and handling it wasn't what killed it...according to what you've found out BethanyM. Good info.

I had one for about 1 1/2 years. I kept it in sand that was about 6" deep and did regularly feed it. I can try to find the article I had on it that was really good. There are many types of sea pens, but only a couple commonly offered.
