Anomalocaris Posted June 11, 2021 Share Posted June 11, 2021 Hello! I have a planted tank that's been set up for about 2 months now (no fish yet, just bladder snails and assorted microfauna), and yesterday after doing a water change I noticed this black branch-like stuff that seems to be growing from my driftwood. It doesn't look like algae, so my best guess is it's a fungus? Does anyone know if this could be harmful? Link to comment Share on other sites More sharing options...
