D. assimilis has been misidentified as Puntius mahecola (Valenciennes 1844) in the past but the identity of both species was resolved by Pethioyagoda and Kottelat (2005 a, 2005b). They inspected the syntypes of P. mahecola and concluded that though valid it isn’t closely related to any Dawkinsia (then the Puntius filamentosus group) but is rather a smaller, silvery fish with a single dark blotch on the caudal peduncle, located entirely posterior to the anal-fin. It’s wi….

This species has been in the aquarium trade since the early 1970s but its precise origin was a mystery until 2003. It first appeared in Ukraine, the common name ‘Odessa’ being derived from the port city of that name, and when it arrived in western Europe was widely considered a hybrid of similar-looking congeners such as P. conchonius, P. ticto and P. cumingii. It was also hypothesised as a subspecies of P. ticto or P. conchonius, and some suggested the fish to be artificially dyed.

Celestial Pearl 'Danio'

The type locality is an area of permanently-flooded grassland formed by the damming of a spring for agricultural purposes. The water is only around 30cm deep, transparent and supports dense growths of aquatic plants, mostly from the family Hydrocharitaceae which includes such genera as Elodea, Egeria and Blyxa. Sympatric species included Devario sondhii, a Microrasbora very similar to M. rubescens, an undescribed Yunnanilus known to aquarists as the ‘rosy’ loach and Channa harcourtbutleri.

D. exclamatio should also have a sub-terminal mouth and lack dorsal-fin filaments but some specimens possess a terminal mouth and/or possess dorsal filaments, and one specimen also had black caudal-fin tips as typically seen in D. filamentosa, whereas the description states that the fin tips are only dusky and lack distinctive markings.

T. hengeli is sometimes seen for sale with the trade name of ‘glowlight rasbora’ due to the distinctive orange patterning on the posterior part of the body but we’ve refrained from using that name here because it’s also commonly applied to Trigonopoma pauciperforatum.
It can be confused with the similar-looking T. heteromorpha and T. espei although on close inspection they’re actually quite easy to tell…

This species is very peaceful indeed making it an ideal resident of the well-maintained community tank. As it places no extreme demands in terms of water chemistry it can be combined with many of the most popular fish in the hobby including other small cyprinids as well as tetras, livebearers, dwarf cichlids, catfishes, and loaches. As always when selecting a compatible community of fish thorough research is essential and its small adult size must be a consideration, however.

These are still regarded as valid by some authorities although it’s widely accepted that they represent variants of R. vaterifloris due to a lack of type material hindering conclusive study. Rasboroides nigromarginata (Meinken, 1956) has also been used to refer to a reddish form in which males differ from other populations in possessing dark fin margins, but the name is currently considered synonymous with R. vaterifloris by most sources despite the fish being rediscovered in 2010.

S. resplendens is traded under several names including ‘Asian rummynose’, ‘rummynose rasbora’ and ‘naked microrasbora’. It can be immediately distinguished from all other Asian cyprinids by the distinctive colour pattern.
The genus Sawbwa is currently monotypic and endemic to the isolated lake basin of Inlé in Shan State, eastern Myanmar.

An ideal resident of the larger, well-furnished community set-up though it might upset slow-moving or timid companions simply by its size.
There are plenty of suitable tankmates including many cyprinids, loaches, cichlids, catfish and characins, but as always when selecting a compatible community of fish proper research is essential. A community based around one of its native countries or river basins…
