I know cholla wood is hard to find outside the U.S but if anyone has seen this growth on it or similar softwoods, is this dangerous or toxic? It looks very slimey but natural. I wonder if there is not enough current in this 40gl with my L-65's that this stuff is growing? One of the adults seem to hangout in the branch so not sure if I should dry it out and rinse it and let the mold die out, since I recently bought smaller pieces online.
