Anyone who keeps Danios know that they love chasing each other all around. Well tonight I noticed all mine were all chasing and circling one of their school mates. It looked pretty violent. My Danios(zebras) Sometimes seem to tuen a shade of yellow and red. The one they were messing with was the only one in the pack that was still black and silver. I tried breaking them up by putting my hand near them and they seemed to stop. Well I just turned my lights on for night time feeding and the one they were harassing was dead and his/her stomach was opened up. Anyone know why this has happened? Are they known for this?
