Care
The Green Slender Rasbora has a very wide natural distribution area which takes in the Mekong, Chao Phraya and Salween basins, the Northern Malay Peninsula, and then Westwards towards the Indus River and Sri Lanka. It is quite surprising, therefore, that this beautiful species is not imported on a much more regular basis. Green Slender Rasboras can attain quite a large size, and as fast-swimmers, they require a spacious aquarium " ideally 4ft long or larger. As a shoaling species, they should be kept in groups of at least 6 specimens in order for them to feel secure. In fact, in their natural habitat, they are known to congregate in vast numbers, so in a roomy aquarium, the more that can be housed together, the better. The aquarium itself should be darkly furnished and include plenty of bogwood and aquatic vegetation, both rooted and floating to create shady areas. The water must not be too hard or alkaline, and a good amount of filtration and a moderate flow rate should be provided. In the wild, these fish are found in a huge variety of different habitats; most of them containing slow flowing waters. This is a peaceful species, but due to its large adult size, should not be trusted with tiny fish or fry. Ensure that the aquarium has tight fitting coverslides, as these Rasboras are expert jumpers.
Feeding
Flake, micropellets, slow-sinking granules, frozen foods such as mosquito larvae, brineshrimp, daphnia, Mysis shrimp etc.
Breeding
Green Slender Rasboras are an egglaying species which will scatter 200-300 eggs over fine-leaved plants. The eggs are said to hatch in 3-4 days. In the wild, spawning takes place during the rainy season in rivers and ponds.
