Rummynose Rasbora
Sawbwa resplendens

Aka: Asian Rummynose, Naked Microrasbora, Rummynose Barb

This name can give the false impression that it is related to members of the genera Rasbora and Microrasbora, but phylogenetic studies have shown to be more closely-affiliated with Puntius and other barbs.  The genus is currently monotypic and likely to remain that way.
                    
The Rummynose Rasbora is endemic to the Lake Inle basin in Shan state, Myanmar.  Aquatic plants grow densely in Lake Inle.  Inle is famed for its floating 'gardens' which provide a valuable habitat for fish species.  The water in Lake Inle is clear, shallow, and has a very fertile, loamy substrate.  The Rummynose Rasboras will grow to a max length of about 1".

The Rummynose Rasbora is best kept in a densely planted tank and is an excellent choice for heavily planted aquariums.  The addition of some floating plants (Wisteria, Frogbit) to diffuse the light entering the tank also seems to be appreciated and adds a more natural feel.  Filtration does not need to be particularly strong as it mostly hails from sluggish waters and may struggle if there is a fast current in the tank.  Temperature in Lake Inle have been recorded to vary between 68 - 75°F.  This species will tolerate slightly acidic conditions but a value of 7.0 - 8.0 is preferable!  Best kept in slightly harder water of 12 - 20°H.

Diet: Likely to feed on small invertebrates, algae and other zooplankton in nature.  In the aquarium it will accept dried foods of a suitable size but should not be fed these exclusively.  Daily meals of small live and frozen fare such as Daphnia, Artemia and suchlike will result in the best coloration and encourage the fish to come into breeding condition.  This is a very peaceful fish especially towards other species.  It will do best when maintained alone or with active, similarly-sized tank mates that enjoy comparable water conditions.

Although it is gregarious by nature it is a shoaling rather than schooling species which develops a distinct pecking order.  Males tend to be engaged in a continual battle for dominance, particularly when maintained in small numbers or in the presence of few females. The best way to minimize this behavior is to purchase more females than males; a ratio of 4:1 or more is ideal or keep in larger numbers.

Sexing:  Males are much the more colorful fish possessing red tips to the snout and caudal fin plus a blue sheen on the flanks which is visible only when the fish is lit in a particular way.  Females are much plainer with a uniformly olive/pale brownish coloration and appear noticeably rounder in the belly when in spawning condition.  This species naturally deposits eggs among aquatic vegetation or filamentous algae.  Apparently the most favorable results are obtained when a group of adults is maintained together as a group and the substrate checked daily for eggs, since the adults tend to eat their spawn.  Temperature also appears important, with the fish failing to spawn at values in excess of 77°F, while general hardness should be at least 20° for both successful spawning and rearing of fry.
