    Just biofilm, it’s normal on new wood. Not harmful, can manually remove it or shrimp and snails will gladly eat it

    That’s fungi growing in the wood that now can expand out into the wet environment around it. Biofilm eaters will love it

    Biofilm. Snails and shrimp will do the job. Or you can scrub it off.
