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…

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 food by larger/more boisterous tankmates while very small fish may be predated upon. Peaceful, schooling cyprinids make good choices as do most gouramis because these tend to inhabit the upper parts of the tank.

Accommodating it in a biotope-style community of West Bengalese fish is more tricky although suitable species from the region include Pethia gelius, Chanda ranga, Trichogaster lalius and T. chuna. Certainly do not combine it with similar-looking, territorial bottom dwellers such as dwarf cichlids unless the tank is very large and never house it with other Badis species as hybridisation might occur. Also note that freshwater shrimp of the popular genera Caridina and Neocaridina, and certainly their young, may be preyed upon.

It is not a gregarious fish and rival males can be very aggressive towards one another, especially in smaller tanks. In these cases only a single pair or one male and several females should be purchased but in roomier surroundings a group can coexist provided there is space for each male to establish a territory and plenty of broken lines of sight. The clever placement of caves can help enormously in this respect; do not be tempted to cluster all the available spawning sites in one area of the tank, for example.

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.

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 …

Reproduction

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 …

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…
