Distribution

The type series was collected close to the town of Raimana in western Assam state, northern India and at the time represented the only known population of the …

Habitat

In the Raidak River it was collected from flowing, cool, shallow (~ 0.6m deep) water with a substrate composed mainly of small rocks with some patches of sand.…

Aquarium size

A single pair or small group can be housed in a tank with a base measuring 75 ∗ 30 cm30 ∗ 12 in or more.

Maintenance

B. blosyrus will thrive in a well-structured set-up with a sand or gravel substrate plus plenty of water-worn rocks and pebbles to provide cover. Plant species…

Water conditions

Temperature: This species is subject to seasonal temperature fluctuations in nature and is comfortable between 15 – 25 °C59 – 77 °F with even greater extremes …

Diet

Badis species are micropredators feeding on small aquatic crustaceans, worms, insect larvae and other zooplankton. They can be a little picky in the aquarium a…

Behaviour and compatibility

Can be kept in a community tank provided tankmates are chosen with care. It is slow-moving with a retiring nature and may be intimidated or outcompeted for foo…

Sexual dimorphism

Females are smaller, have duller patterning and a noticeably shorter, rounder-looking body profile then males. Males also develop slightly extended finnage as …

Members of this genus are cave spawners that form temporary pair bonds and are not usually too difficult to breed provided the tank is arranged correctly (see 'tank set-up'). Other species are best omitted if you want to raise good numbers of fry although in a mature, well-furnished community a few may survive to adulthood. Either a single pair or a group of adults can be used but if using multiple males be sure to provide each with a cave to defend. Water parameters should be within the values suggested above. Feed the fish with plenty of live and frozen foods and spawning should not present too many problems.

As they come into breeding condition rival males will become increasingly combative and begin to display courtship behaviour towards females entering their chosen territory. During this process they display some wonderful changes in patterning with the body intensifying in colour. The locking of mouths is also common; the male literally attempting to drag his partner into the cave. A receptive female will enter and spawning takes place with usually 30-100 eggs being laid.

Post-spawning the female is ejected and the male takes sole responsibility for the eggs and fry, defending the territory against intruders and fanning the brood with his fins. If you wish the other adult fish can be removed at this point although it is not absolutely necessary yet. The eggs usually hatch in 2-3 days but the fry do not become free swimming until they are 6-8 days old and may not leave the vicinity of the cave for another week or so after that. From then the adults (parent male included) may begin to regard them as food and are best transferred to a separate tank. The young fish are quite sedentary for the first few days meaning microworm is the ideal initial food but once they are visibly swimming in the water column Artemia nauplii can be introduced to the diet.

Where does this come from?

My own experienceFor example, I've kept twelve in a planted 60 cm tank since March 2024.A website I sawFor example, an IUCN Red List assessment, a museum catalogue or a FishBase page.A paperFor example, Marshall et al. (2011), Water temperature differences in interfluvial palm swamp habitats of Paracheirodon axelrodi and P. simulans.A book, or something not onlineFor example, Tappin (2010), Rainbowfishes: their care and keeping in captivity.Something already on the profileFor example, the Behaviour and compatibility section already says this.

Notes

Like most badids this species is poorly documented and has yet to find significant popularity in the aquarium hobby. It is easily confused with B. assamensis a…
