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.

Did you have them out of the water at any point? Even transfering them out of the bag?

[Discustopia]

actually, even bubbles from your skimmer that stray into the tank or if your sump cavitates and blows bubbles are dangerous

As the bubble rises through the sponge it kills the surfaces it touches - sensitivity varies sponge to sponge. especially deep water spponges are not used to any air bubble contact

no i was informed not to let air touch them. I am going to try to cut off the dead so it does not spead. Hopefully this will stop the spread.
