Anyone know anything about sea sponge?

sounds like they aren't doin so hot. got pics?

sponges are super delicate and VERY finicky about water quality. when you introduce them into the tank, you cannot allow ANY exposure to air. air gets in, they can't expel it, and they die. these are by no means suitable for any one but experts and even they have troubles with sponges. they also require pretty much constant feeding which most aquarists wont bother to or can't do.
