Distribution

The distributions of Danio albolineatus is rather extensive throughout South Asia. It can be found in Burma (Myanmar), Thailand, Sumatra, Malakka and India. Here it inhibits rivers and streams with a current that ranges from rather weak to strong. However, this species is almost always found in waters with a high amount of plants.

Description

This species is also called, pearl Danio. Danio albolineatus can, amongst others, be found in ponds. These ponds, often, have a substrate of plant residue. The fish themselves live in schools. Due to the fact that they need to be kept with multiple specimens, the aquarium should not be too small. 70*30*30 cm is an absolute minimum for this species. Keeping them with too little fish to create a school or keeping them in an aquarium that is too small, will negatively influence their health.

The name albolineatus consists of the part albo, meaning white, and lineatus which means stipes. Danio albolineatus has, however, no white stripe on its body. Therefore, the name of this species might seem strange. Placing specimens of this species in formaldehyde will make the name more clear. Dead specimens that are stored for research will start to change their colours. For this Danio species, this storage will result in a white stripe along the body.

So far, this species has seen a lot of different descriptions, resulting into different synonyms for these fish: Nuria albolineata, Brachydanio albolineatus, Danio albolineata, Branchydanio albolineatus, Danio stoliczkae, Danio pulcher, Danio tweediei and Danio tweedie.

Diet

Danio albolineatus is an omnivorous species and not a picky eater. It will eat almost anything, including fabricated foods. However, to keep the fish in an optimal condition, a varied diet should be presented that includes living foods.

The aquarium

The aquarium should be decorated with a lot of plants, providing enough hiding places. The fish prefer an aquarium located in the sun with enough light and a relatively high water temperature (21-25 degrees Celsius). In these conditions, the fish will be in their best health. Danio albolineatus is not particularly sensitive to differences in water chemistry. However, occasional water changes are recommended.

Breeding

The breeding aquarium should have a minimum size of 40*25*25 cm. The water iself should have a relatively low water hardness. This can be created by adding distilled or rain water to the aquarium. The substrate should consist of sand which will need to be covered with algae, moss or aquatic ferns. The temperature of the water should be increased to 25-27 degrees Celsius.
In this aquarium one male should be combined with two females. When the spawning is completed will it be necessary to remove the fish from the tank. Additionally, the tank should be placed in such a way that he light in the aquarium is dimmed. The eggs are rather sensitive to bright light. 2 to 3 days after spawning, the eggs will hatch. The precise duration is, however, dependent on the watertemperature.

Initially the fish should be fed using small food, such as infusoria. However, after four days, one can start using artemia nauplia. An important aspect of making the fry grow large and strong is keeping the water chemistry proper. Fry is very sensitive to deteriorating water conditions. So frequent water changes must be done. The total amount of fry can be as large as 300 to 400 individuals. These fish need to be placed in a bigger tank as soon as possible to give them enough space to grow. Additionally, the water temperature should be as constant as possible.
