OK to place Tree Sponge in substrate? *pic inside*

[jimrawr]

So I bought this Tree Sponge today, and I want to place him low away from the MH lighting. Is it ok to keep him in the substrate like this? Part of the sponge(about an inch) is burried so its not getting and light or waterflow at all.

One more question, on liveaquaria it says to feed it disolved organic food. What exactly would that be?

I have no clue on this. But try posting it in the "Other Invertebrates" forum. They do sponges there.

disolved organic food=phytoplankton.

Thanks I will

Some sponges might consume smaller phytoplankton. Other food sources might include bacteria and small cellular remnants and similar-sized organic matter. I wouldn't bury the sponge that way. I'd just glue it onto a piece of live rock and support it that way. The buried portion might die and rot.
