Betta sp. Bung Bihn
Gonin, Herve and Jacques Laird. 2002. 
|Where Found||Vietnam, 80 km from Saigon in Cuchi region on the road from Cambodia in stagnant water and muddy ricefields. A Betta affin. imbellis is found here also. |
|Miscellaneous Information||pH range:||
pH 6.5-7.2 ]
|kH range:||6.6-10º |
|Temperature range:||27ºC. (~80ºF.) |
|General notes on Water Chemistry:||EC 300-400 µSiemens (TDS 195-260 ppm). A mixture of aged (dechlorinated) tap water and rain or reverse osmosis water is considered optimal. |
|Reproduction:||Mouthbrooder. Easy to breed although considered not very prolific. Water conditions for maintaining this species are quite adequate for breeding purposes. Spawning may not be readily apparent except when one or both fish may disappear, reappearing after 10-13 days of brooding when several fry can be observed. The eggs are white ovals measuring 1.5-2 mm. The new fry are large at 6-7 mm and can be fed brine shrimp nauplii which is supplemented by infusoria in the Riccia and decomposing organic matter. Their growth is rapid and it is extremely important that the aquarium is covered well with plastic sheeting to insure that the fry are not subjected to cold air at the water’s surface especially at 15-20 days when the labyrinth organ is developing. B. sp Bung Bihn is sexually mature at 5 months and just over 3 inches (8 cm) in length at this stage. |
|General notes:||Suggested aquarium size of 80 liters minimum (21 US gal.) and long as opposed to tall for increased surface area; numerous hiding places composed of roots, coconut shells, etc.; substrate of boiled oak leaves; floating plants such as Riccia fluittans to screen out strong light and several bunches of Hygrophilia or similar plants; iron supplements for the plants, and one air driven box filter in each rear corner providing good filtration without strong turbulence. 
Feeding presents no difficulty as this species has a large appetite and eagerly accepts all flake, live, and frozen foods. 
|Taxonomy:||“Hoek Hui Tan of Singapore University comments these fish are likely to be B. prima although somewhat redder than those he has seen from Cambodia or Thailand.” |
