Well you read the title.

Anyone else notice them zipping around the tank at certain times of the day?

The only time that mine "zip" as opposed to just normal swimming is when the Co2 gets real high, like when i've turned it up LOL i had them jumping out the first time i did it! Nowadays i just increase it slowly :rolleyes:

Zippy amanos in my experience means either a female has released pheromones into the water ready to breed, or as per what Dan said your CO2 levels are too high (even more chance of this if they are surfing in your filter outflow).

Some of mine are carrying eggs.
No chance of ammonia spike.
Mayyyyybeeee a little high co2. its usually just before the main lighting goes off and only 1T5 is on. But surely they would carry on going nuts after lights out as co2 gets even greater?
Mine calm down after a while.

Think it could be randyness from pheromones.
