Danio tinwini

Danio tinwini is a small, easy to keep species. These fish have a remarkable pattern over their body that makes it a nice species to watch in an aquarium.


Danio tinwini

Danio tinwini was first described by Kullander and Fang in 2009. Before this description, this species was already available in many stores. In those stores, these fish were sold under the name “Danio sp TW02”.
The scientific name: tinwini, is a reference to U Tin Win. he was a friend of the aforementioned researchers. In addition, did he provide a substantial contribution to the research of the fish species from Myanmar (Burma).


These tiny fishes belong to the smallest Danio species. However, due to its appearance, it is distinct from other species. The body of Danio tinwini is white to yellow. The pattern on the body consists of four horizontal dotted lines. These lines transform to solid lines once they reach the anal fin. The stripes start after the operculum and, from there, run over the entire body including the caudal fin. At the anterior part of the belly, a large white blotch can be seen. Dorsally, the fish are brownish yellow. The fins are completely translucent with the exception of the blue to black dots. These dots are not found on the pectoral fins.

Distribution and Habitat

Danio tinwini is found in Mochaung, which is a small stream in Kachin state in Myanmar (Burma). This stream is connected to the Irrawaddy, the largest river in Myanmar. This species is mainly found in those ports that have a weak current.


Danio tinwini is not hard to feed. These fish will accept almost any food that is offered, including factory foods. However, feeding live or frozen foods occasionally, will improve the health of the fish.

The Aquarium

Since this species mainly lives in parts of rivers where the current is relatively weak, a strong current is not needed in the aquarium. In contrast, too much current may blow these fish throughout the tank.

The aquarium can be decorated with plants and other materials such as rocks and wood. A densely planted tank will enhance the coloration of Danio tinwini. Similarly, a dark substrate will improve the colours as well. Do keep in mind to provide a lid on the tank. These fish tend to jump out of the aquarium.


Danio tinwini is not hard to breed. In order to get a high yield, however, a special breeding aquarium should be set up. This aquarium should contain a high amount of plants. This will provide a good substrate for the fish to spawn on. Other solutions such as a substrate of marbles or a grid above the substrate, will also prevent the fish from eating their eggs. The water in the aquarium should have a low alkalinity with a pH that is neutral to slightly acidic. The temperature will need to be raised to the outer boundaries of the temperature range of these fish.

When the fish are ready to breed, they can be transferred to the aquarium. By feeding them a lot of live and frozen foods, these fish will be encouraged to spawn. Furthermore, if the aquarium is only half full of water, it can be slowly, over the course of several hours, be filled with colder water. After refilling, Danio tinwini should start to mate in the next morning.

As Danio tinwini will tend to eat their eggs and fry, it is best to remove the fish from the tank after spawning. Additionally, the current should be non present at this point in time. The fry will not jet be able to handle the water flow. 24-36 hours after spawning, the eggs will hatch. A few days after that, the fish will start to swim freely. At this moment, the fry can be fed with infusoria. Artemia nauplia can be provided once the fish are large enough to handle them.
