General Description
M. gatesi, commonly known as Burmese Golden Rasbora, is a peaceful species that is often traded as such in the aquarium trade. It can be distinguished by its possession of hyaline dorsal and anal fins plus 13-14 branched anal-fin rays. M. gatesi belongs to the Cyprinidae family and is classified under the order Cypriniformes. The species is relatively small, with mature adults typically reaching sizes of less than 2.3cm in standard length.
Aquarium Setup
When setting up an aquarium for M. gatesi, it is recommended to maintain them in a densely planted tank, making it an excellent choice for carefully aquascaped setups. Filtration should be relatively gentle, and the addition of floating plants and driftwood roots or branches can help diffuse the light entering the tank. For specific water conditions, refer to the table provided.
Behaviour
M. gatesi is a schooling species by nature, so it is best kept in groups of at least 8-10 individuals. While very peaceful, it is generally recommended to maintain this species alone or with other comparably-sized species that enjoy similar conditions. In a group setting, males will exhibit their best colors as they compete for female attention.
Feeding and Diet
In their natural habitat, M. gatesi likely feeds on small invertebrates, algae, and zooplankton. In the aquarium, they will accept dried foods but should primarily be offered small live and frozen fare such as Daphnia and Artemia. Providing a varied diet will help ensure the overall health and vitality of the species.
Reproduction & Dimorphism
Reproduction in M. gatesi involves the scattering of eggs randomly among aquatic vegetation without any parental care. Successful breeding has been observed in aquaria with related species. Mature females tend to be larger and deeper-bodied compared to the more compact and vibrantly colored males.
Habitat and Distribution
The species is known to inhabit the lower Irrawaddy River basin in Myanmar, including tributary drainages such as Sittaung and Bago. M. gatesi is possibly endemic to the Irrawaddy Delta region and is often found in sluggish and standing freshwater environments like rice paddies, swamps, weedy ponds, and ditches abundant with dense submerged vegetation. The climate of its habitat is warm and wet, with varying water levels throughout the year.
