On one of my driftwood pieces, there is long strands of white string coming out of a hole, that sort of look like roots (but i doubt it is). Theyve been there for a couple of weeks, and are spreading. I cant manage to get a pic up right now, but it just looks like white strands of thick string creeping out.
Could it be slime mold? Coral fungus? I'll try to get a pic up though..
Thanks,
