Well I have a 33" tall orange sponge that I have kept alive for almost 8 months now. well the top part is starting to die. If anyone has a use for this sponge they can have it. But you have to bring your own container (remember its 33" tall and like 4" wide). I will supply the sw in wich the sponge is living in as this tank is going to be converted back to fw sometime in the near future. The top 6" or so is turning really white. heck if someone wants to try and save it by all means try =].
