I have one male and four female zebra danios and the male keeps chasing the females around and it's looking quite aggressive. Is this normal with spawning or are they attacking each other? There's nine neon tetras in the tank as well and the danios don't seem to be bothering them. It's around noon rn, if this is spawning is that a normal time? I thought they spawned at night and early morning. Should I be concerned or just let them do their thing? It looks like the male is just chasing the females and almost looks like he's nipping them.
