I have had my Zebra Danios for two weeks now, and as I watch them every day I've noticed some really weird behaviour:
The mates are loyal to eachother: same male, same female per spawn.
They spawn like clockwork: Every 11 days, as soon as the lights go on.
A fish hierarchy: There is one dominant female who likes to push the other fish around and no male tries to mate with her.
Adaptation: The new fish introduced to the tank will not come up when food is dropped into the tank. Instead they wait to see what the other fish are doing and about 5 minutes later will join them at the surface to discover no food is left and the next time join the rest of the school immediately at the surface.
Fry: Not very intelligent ways of evolution considering 99.9% of each spawn are eaten unless I intervene. Fry do not care about one another. They prefer to be in a small area/tank, floating plants help, filtration is preferred but not necessary, air stone not necessary, light is preferred, room temperature is fine, do not need to eat fry food but will live off of the plant.
Those are my observations after 14 days.
