I looked them up and apparently they are harmless.
I saw Sam eating something and thought nothing of it.. when I noticed them stuck to the glass and thought maybe some hair or fluff had gotten in the tank.
But then I noticed that theyre moving.
I think they are planaria?
Sam seems to enjoy eating them and everything Ive read says they are harmless. I recently switched to a cycled tank with gravel instead of pebbles. So naturally theres more bacteria and natural stuff happening in here, I can accept that.
As long as theyre really harmless then thats fine.
Is it okay for Sam to be eating these things and are they providing him with any nutrition?
