Why are my neons fighting?
I've had these 5 tetras for over 3 weeks now. Everyday I see them do this little chase or lunge at each other. Is it territorial or mating? (I doubt it's mating because I've never seen any of them lay any eggs...)
They're all eating well and behaving normally otherwise. They had Ich a few days after I put them in the tank but all better now.
They're in a (roughly) hand-made tank that's 23.5L, 45.5cm long. My LFS said 5 would be fine in there with 5 pygmy corydoras. Now I'm reading online that the tank is probably too small for both?
