Geographic History

This little fish comes from Sumatra, Burma, and Thailand. They are found in small, clear hill streams.


These active little guys love to swim across the length of your fish tank and require open water in the middle. They will dart in and out of plants on the sides and back of your aquarium for spawning and cover. Provide them with a well lit aquarium and a tight fitting hood.


Pearl Danio are good neighbors in a community tank stocked with active fish. They tend to be fin nippers so don't keep them with long finned fish. They can be rather shy and larger aggressive fish will scare them into hiding.


Males are slimmer, more torpedo shaped, and have brighter colors than the females.


These are school fish and work best in groups of five or more. Smaller groups are more aggerssive fin nippers. They love to chase each other and sometimes jump out of the water. Make sure you have a tight fitting hood on your tank so your little buddies don't end up on the floor.


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. The breeding tank should be dimly lit. 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.
