I literally added Neon to his 10 gallon tank last night and he has a small cut on his head )=)=)= I don't know what could have done it!
Help me with him though. I think he just got it as I just noticed it. I'm wondering if I should move him to his 2.5 gallon or not seeing as I added him yesterday. The ammonia is kept in check, but my poor fishy! Help!
This is pretty serious, please respond! I don't want him to die from an infection or something!
