My driftwood progression went from the nice light and dark mixed mopani driftwood piece, pic one.
Then I boiled it and it turned all red, not so nice as the blonde wood colour that it had.
Put it in the tank and it very quickly grew some sort of fungus, at least I am assuming that it was a fungus by the look of it. I was considering that the wood may have to be removed and relegated to a dry display piece. pic three but with some clean spots. The pond snails wouldn't touch it and the trumpet snails like the sand better.
In pic three the clean spots are thanks to four tiger snails. I dropped them on it specifically and have only had to move two back on as they seem to really like the stuff growing on the wood.
Pic four is the end result, the tigers are still working on the last of it and it is looking much better. If it doesn't keep growing back then the wood may stay. Otherwise I have two lattice rock pieces that may get substituted. It's a shame if that is the case as I like that white quartz egg shaped rock that I wedged into the wood.
Yes, this leads to a question... if the snails eat the fungus is it reasonably safe to assume that it is not some harmful to the fish fungus?
