So I notice yesterday at night that my betta has this two markings on him around his face and on top of his face. I’m not sure what this could be, i know he didn’t have this before. Could you guys help me figure out what this is?
These could be marks from stress, or a sign of inactivity or too much activity in the tank (swimming around frantically, knocking into wood, rocks, decoration, or plants). I have a female betta with a similar spot on her head, and she was the runt of the spawn.
