Name: Rasbora dorsiocellata
Common Name: Emerald Eyed Rasbora, Eyespot Rasbora
First Described: Duncker, 1904)
Habitat: Southern Thailand, Malaysia, Sumatra and Borneo. Found in dark water streams connected to peat swamps in the forrest. Due to the surroundings, these waters are very soft and acidic with pH levels as low as 4.0)
Suitability for home aquarium: A hardy, peaceful fish that requires moderate care. Suitable for the community aquarium.
Maximum size: Adults can reach up to 1.5 inches or 3.5 cm in length. Females tend to be a little larger and slightly rounder than males.
Water requirement: A hardy fish with a wide range of parameters. With that in mind, consistency is very important. All fish do better when provided with steady water conditions within a specific range.
- pH between 4.0 -7.5
- KH between 3-7
- Temperature between 73-79F/22-26C
Diet: A natural micropredator that consumes tiny insects and crustaceans in the wild. A diet that is easily replicated in the home aquarium setting. Dry foods containing insect meal should be offered daily. The Emerald Eyed Rasbora is officially an Omnivore so balancing their diet with plant based foods, insect meal and live foods will ensure you get the best from these little gems.
Behaviour: A peaceful schooling fish that thrives in groups of 10 or more. When kept in larger groups, you will see a more confident group of fish displaying their best colours and most natural behaviours.
Breeding: It is worth noting that these fish do not display any parental behaviour at all and will eat any eggs they may see in their aquarium after spawning. They are what we call egg scatterers and as a result, if a purposeful attempt is being made to achieve successful breeding, both parents should be removed as soon as the spawning has been completed.
To initial breeding, first identify both sexes and place them into an aquarium on their own. The aquarium should have thick mesh or a grassy matt placed on the base of the tank. The idea is that when the female releases eggs, the fall to the bottom and become hidden from the parents. We advise raising the temperature to around 25-26C and remove approx 25% water. Reintroduce water at a very slow speed and if possible, simulate rain or a trickling effect. The potential pair should be fed quality live or frozen foods multiple times throughout the day.
Spawning will take place multiple times until all eggs have been released and the female is noticeably thinner. This is when parents should be removed. If successful, you should have free swimming fry within 48hrs.
Great high quality little fish very good price
