I have some zebra danios that are just too fast to let others eat. they even go after sinking foods for my cories. any advice on how to slow down their eating or how to get them to let other fish eat? Thanks

Why do they lose their colors at night? they look very pale at night

1. Feed the danios on one side and the cories on the other, or you could get a clean plastic tube and run it down until its just above the aquarium floor and feed the pellets down the tube so the danios cant reach them.

2. The danios and almost all fish lose their color at night because they are relaxed and do not need to show color at night. It's basically a sleep-like state they go into and the become pale as they "sleep"
