Devario sondhii
Devario sondhii is naturally found in Myanmar, located in Southeast Asia. The fish can be found in the Salween River, in places with clear water and densely overgrown with plants, at a depth of about 30 cm. This fish species first appeared in the trade in the mid-2000s. Due to the great similarity in coloration, there was some confusion at first with the Microrasbora rubescens and both species of fish were supplied to the retail network under the same name. In general, Devario sondhii easy to keep and can be recommended to beginners aquarists.
The basic body coloration of the fish is silvery yellow. The body is weakly contrasting longitudinal stripes of lilac and gold. All fins are translucent. In contrast to the males, females have a rounded abdomen, larger in size and less bright coloration. The maximum size of the fish is 4-4.5 cm.
Keep Devario sondhii should be a group of 8-10 individuals. For such a number of fish need an aquarium of 60 liters. possibly keeping Danio in a common aquarium with other peace-loving fish similar in temperament and size.
The aquarium should be densely planted with plants, including floating, which will serve as a good natural light filter. Water movement should not be strong.
Water parameters: temperature of 20-26° C, hardness dH 1-6°, pH 6,5-7,5. Fish are intolerant of organic contaminants, which requires a high-performance water filter. Just need a weekly substitution of up to ½ of the aquarium water with fresh. The aquarium should be covered with a lid on top to prevent the fish from jumping out of it.
The main food of Devario sondhii in nature are insects and their larvae. In the aquarium, the fish eat most foods. Dry food can be used as a staple food, but at the same time, diversify the fish diet with live or frozen food such as Artemia, Daphnia and bloodworms. Feed the fish twice a day.
Reproduction
Like most small carp fish, Devario sondhii do not show concern for their offspring. Under acceptable conditions, the fish periodically spawn in a common tank and a small number of fry emerge without interference.
However, if you want to keep the stock of fry, it will require a small spawning tank of about 20 liters, which should be filled with old water from the main tank. At the bottom of the spawning aquarium have a separator mesh or a densely planted aquarium Vesicularia dubyana.
At spawning land 1-2 pairs of fish. spawning usually occurs within 24 hours. Immediately after spawning manufacturers put off. The eggs are incubated, depending on the water temperature, 24-36 hours. Hatched larvae are sedentary, but after 2-3 days begin to swim and feed.
The fry are fed live dust, micro worms, artemia, and powdered food designed for fry fish.
The Devario sondhii has a lifespan of about 3 years in aquarium conditions.
