HELP I need info on sponges PLEASE

[justinl]

there are some sponges that are exposed to air regularly just from the tides. But most sponges will perish if they get air stuck in them. just goes to show you cant really generalize. How long were they out of water? Assuming the sponges you have are the regular hitch hiking ones, they will likely survive, feeding or not. pics?

most sponges (only a few freaks of nature) are suspension feeders that feed on the very smallest of microplankton, phytoplankton and dissolved nutrients.

They are a filter feeder and don't usually like bright light.

I have a number of different hitch hiker sponges, one that has actually grown rather large in the past year. I've never done anything for them and they seem to do just fine.

Biggest thing for sponges is an established tank. My live rock came with pink and with white encrusting sponges which doing fine.

sponges are great.....you get to benefit from their filtering and require really nothing from you.

I have a bunch of hitch hiking ones on the bottom of one of my rocks, it seems that the only places they grow in my tank are where it's complete shade, they grow like mad though (pink ones especially), i never bother feeding them or anything either.
