Picture by Ye Hein Htet (Hein Aquarium)
Explanation of scientific name: The genus Sawbwa referred to Myanmar native name of former ethnic leader of SHAN states, similar to Maharaja of Indian States. The specific name, resplendens refers to brightness.
Original description: N. Annandale (1918), Fish and Fisheries of Inle Lake Rec. Ind. Mus., Vol. xiv.
Type specimen: Sawbwa resplendens
Type locality: Inle Lake, Southern Shan States.
Distribution: Inle Lake and Kaya State.
Habitat: The fish form in large shoals among dense vegetation in the clear water of central region of the lake as well as peaty water near the edge.
Characters: Body is rather elongate and compressed. Mouth is small terminal, oblique and no barbels. Second and third simple ray of dorsal fin is osseous, stout and serrated in the middle region. Pectoral fins are small. Caudal fin is strongly forked. The body is naked. The color of the body of the male is silvery grey or steel blue. Bright red spots are on each lobe of caudal fin and on the nose. The female has no attractive color. Maximum length is 25 mm for the adult. Sex differences: Same description as in character.
Aquarium keeping: The fish can be kept in community tank. However, the beauty of the fish can be more appreciable when they are kept in species tank with thick aquatic plants. The tank size should be 100 x 30 x 35 cm. The water hardness, dH should be 1o -2o and pH should be 6.8. The temperature ranges 22o – 25o C.
Spawning: For breeding purpose, 60-100 liters tank is the best choice for a pair of Sawbwa fish. Other requirements are a small sponge filter and clump of Java fern. The water should be slightly acidic (pH=6.5-6.8) and low minerals (Conductivity=5-10 μS). Size of eggs is almost about a millimeter in diameter. Sawbwa resplendens spawn frequently, perhaps daily, however, number of the eggs are not more than one to two dozen at a time. The incubation period is approximately 2 days at 26o C. Two or three days would take for free swimming of the fry. The length of newly hatched fry is approximately 3.5mm. Primary food is infusoria (microscopic organisms) and later newly hatched brine shrimp nauplii are basic feed.
