Paintbug New member Feb 19, 2008 #5 its a sponge. it will grow, and become pretty cool looking after a while. nothing to worry about.
The_Browns New member Feb 19, 2008 #6 Definitely looks like a sponge. Don't let it be exposed to air, sponges usually die when coming in contact with air (being out of the water)
