Like most badids this species is poorly documented and has yet to find significant popularity in the aquarium hobby. It is arguably the most attractive member of the genus and we hope to see it more widely available; the fish in our images representing what is thought to be the only batch exported from Myanmar to date. It is most closely related…

Like most badids this species is poorly documented and has yet to find significant popularity in the aquarium hobby; to date it has only been exported in very limited numbers. It was for a number of years known as Badis badis siamensis and will be seen labelled as such in older literature. Within the genus it is most easily confused with B. khwae and B. ruber but can be identified by the flank patterning which consists of rows of horizontally-arranged dark markings. In B. ruber these appear mor…

Like most badids this species is poorly documented and has yet to find significant popularity in the aquarium hobby, though given its restricted natural distribution it is unlikely ever to be available in large numbers. Within the genus it is most easily confused with B. ruber and B. siamensis but both these species have rows of dark spot-like markings on the flanks which are lacking in B. khwae. The three also differ in the shape of the dark marking on the caudal peduncle; in B. ruber it is rel…

Like most badids this species is poorly documented and has yet to find significant popularity in the aquarium hobby. Within the genus it is most closely-related to B. pyema but the two are unlikely to be confused as B. corycaeus is much the deeper, darker-bodied fish.

Prior to 2002 the family Badidae included just five species of which only B. badis and, to a lesser extent, Badis dario (referred to as B. bengalensis by some sources) were popular in the aquarium hobby. However an extensive rev…

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 at first glance as the body patterning of the two is almost identical but can be distinguished by its slightly smaller adult size, noticeably elongated, more well-developed jaw profile and some other, mostly internal, meristic characters.

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. blosyrus at first glance as the body patterning of the two is almost identical but can be distinguished by its slightly larger adult size, noticeably shorter jaw profile and some other, mostly internal, meristic characters.

Known only from southern (peninsular) Thailand with the type series originating from a swamp some 83 km north of Surat Thani city, Surat Thani province. It’s been recorded at additional locations, all within the lower Tapi river drainage on the Gulf of Thailand slope of the Malay Peninsula. In the description Conway and Kottelat (2011) report the occurence of a similar-looking, possibly conspecific fish on the Andaman Sea side of the Peninsula, close to Trang province.

The Iranian Plateau is home to a diverse group of Aphanius with four species already described and several awaiting description. These are among the most ancient in the genus having divereged away from a common ancestor around 20 – 24 million years ago. Among them this species is most closely related to A. sophiae from the Kor River system but can be distinguished by differences in patterning. Males of A. sophiae lack the characteristic darkcolouration seen in A. vladykovi and females possess a …

Prior to its description this species had been considered a form of A. anatoliae and also referred to as A. sp. aff. danfordii but collections in the early part of this century motivated new studies and resulted in its elevation to full species level. Phylogenetic analyses have shown it to represent the sister group to all other Anatolian Aphanius spp.

The Anatolia region represents a centre of diversity for the genus with ten endemic species described to date. These are thought to have diverged …

All Algerian Aphanius populations were considered to be representative of A. iberus until this species was described in 2006. It differs both morphologically and genetically from A. iberusand A. baeticus, probably diverging about 5.3 million years ago during the opening of the Straits of Gibraltar. It is most easily distinguished by the distinct mottled body patterning which in males of the other two species forms distinct vertical bars and in females dark spot-like markings. A. iberusis now k…
