Comments: This is a Premium Pet Fish, and we never see Premium Danios like these in any of the live fish stores or the online stores that we visit.

Premium Pet Fish are more energetic, hardier, and have brighter colors with a beautiful metallic sheen.

Origin: This species was discovered in 2009 in Myanmar, which is a country in Southeast Asia.

This fish is now being produced in large quantities by fish farmers, and it lives in many aquariums throughout most of the world.

But this is still a relatively rare aquarium fish.

But almost all fish continue to grow throughout their entire lives, so it's possible that old fish may occasionally grow to be unusually large.

However the largest we've seen so far are all 1" long or less.

Someday we might see one that's more than 1.2" long. ;^ }

Behaviors: These little guys are active, and the males energetically quarrel with each other.

This fish is skilled jumper. So their aquarium must be tightly covered.

Compatibility: Some recommended tank mates include small fish like Harlequin Rasboras, Neon Tetras, Cardinal Tetras, Guppies, Endler's Livebearer, Corydoras Catfish, Honey Gouramis, etc.

Temperature: They can live pretty well from about 74 to 82 degrees F., but they're probably most comfortable at about 78 degrees F.

Feeding: Premium Fish Food Flakes.

Water Conditions: This fish seems to be tolerant of a wide range of water conditions. Probably a pH of about 7 with moderate hardness is best.

Most water in the US seems to be OK, so it's probably best NOT to adjust the pH or the hardness of the water.

Here in our facilities the water is hard and the pH is usually about 7.8. We ship them in this water.

Aquarium Size: It is probably best to house these fish in at least a 20-gallon tank, but bigger is better, because the males quarrel with each other. Keep at most one fish per gallon.

Decor: They do not need gravel, and a layer of gravel more than 1/4" thick will usually fill with bits of uneaten food that will contaminate the water.

Live Plants are beautiful and improve the water quality.

Aquarium Filter: Bio-Wheel Filters are highly recommended.

A Penguin 200B Filter in an aquarium with 20 to 30-gallons of water is just right for these fish.

The addition of Lava Rocks will keep nitrates in the ideal range.

Life Span: They will probably live for a few years with good water and good food.

Gender: The mature males are more colorful than the females, which become plumper, as they fill with eggs.

Breeding: Danios scatter their eggs on plants or special breeding mops made of yarn.

Popularity: This is a relatively new aquarium fish that's steadily gaining popularity as a good fish for small aquariums.

Names: The scientific name is Brachydanio tinwini.

Variations: We haven't seen any.
