This little fish comes from Myanmar. It lives in small, narrow streams in the hills. They prefer rocky bottom streams surrounded by forest.
Glowlight Danio likes an aquarium with subdued lighting and tall plants. You should provide lots of swimming room in the middle. Keep a tight fitting hood on any aquarium where you keep these little jumpers.
These guys do best with other tiny fish. Keep them in groups of six or more because they will swim in schools. To avoid fin nipping, don't keep them with long finned fish. Larger fish, especially Cichlids, will eat these little guys.
The males are smaller than the females but they have brighter colors. Females have a fatter body.
This Danio will establish a "pecking order" in their school. They will chase each other around, sometimes jumping out of the water. Don't be surprised if they are a little aggressive toward each other when you first put them in the aquarium. This behavior will settle down as they figure out who is the lead fish.
When females are ready to spawn, they will become fatter. Move a group of several females and a couple males to a ten gallon tank that has been filled 1/4 way from the bottom. Adding marbles to this tank for substrate allows the eggs to fall into spaces that the adults cannot reach.
Watch for the fish to chase each other around and spawn. Once the eggs are scattered around the bottom they fall into the marble substrate. After a couple hours, remove the adults from your breeding tank.
The eggs will hatch in about 36 hours. The fry will be swimming freely in another 36 hours. They should be fed crushed flake and Inforusia.
Be prepared for a lot of fry. The females lay several hundred eggs and can repeat the spawning process every two or three days.
