The tank was checked each day for the next four or five days and although the two fish seemed interested in each other, there were no eggs. I added the male a day later and waited for eggs. Another reason I did this was that the first time I tried to breed these fish (about a year ago) I put the pair in the tank at the same time and the male drove the female so relentlessly that she died. The female was put in the tank first in order to allow her to adjust and feel comfortable. The water consisted of about one third RO water and two thirds tap water which resulted in water of about 200 micros. I used a bare ten gallon tank with a spawning grid on the bottom as well as a couple of sinking mops. Although a five gallon tank may do, a ten is probably better. A breeding setup for these fish is typical for the group. columbianus is neither the easiest nor the hardest tetra to spawn. This may be true but I have found that H. One text says they are “egg scatterers, even on bare glass”. The fish are likely being bred commercially since the collection sites are said to be extremely remote and not easily accessible.Īquarium breeding, according to the literature is easily accomplished. For some reason, the price of the Columbian has remained high (for this type of tetra). I’ve kept them with considerably smaller fish and the Columbian Tetras haven’t bothered them.įor the past few years these tetras have been a common sight in pet shops and a tankful of them makes a nice display. In my experience they make quite acceptable community fish. All in all they are distinctive and attractive fish. Both sexes, as the common name implies, are shades of blue and red – the blue mostly in the body and the red in the fins. Males exhibit more fin development than do the females but until fully grown they are not the easiest species to sex. The fish grows to about two or two and a half inches with the males growing a little bigger than the females. Things stayed this way until late 2001 when Zarske and Géry definitively described the fish as Hyphessobrycon columbianus – a much better name for a fish from Colombia, even though the country’s name is misspelled. It would seem strange that a fish found in Colombia and called the Columbian Tetra would have the specific name ecuadoriensis! Some time later it was suggested that it was not a Hyphessobrycon at all but rather a member of the genus Astyanax. It was described as being “close to” Hyphessobrycon ecuadoriensis some in the hobby conveniently ignored the “close to” and used this name anyway. Only available for the past few years, the fish was first collected in a small stream upstream from Acandi, in the Rio Acandi drainage system near the Atlantic coast of Colombia. The Red/Blue Columbian Tetra will accept many small foods such as brine shrimp or daphnia, freeze-dried bloodworms and tubifex, micro pellet food, and a high quality flake food.The Columbian Tetra or Blue-Red Columbian Tetra is a fish with a very chequered past, considering its relatively short life within the hobby. After spawning remove the parents or they will eat their offspring. Slightly acidic water is best for optimal breeding habits. Red/Blue Columbian Tetras will breed occasionally in an aquarium setting and a hospital or “breeding tank” will be necessary. This species does best with soft slightly acidic water with high filtration. Rocks and driftwood help mirror its natural habitat and will help to reduce stress on this fish. Perfect for the community aquarium, this hardy Tetra will be a great choice for the beginner to the expert aquarist.Ī planted aquarium of at least 20 gallons will be the ideal environment for the Red/Blue Columbian Tetra. The Red/Blue Columbian Tetra gets its name from its bright red tail, and its reflective body. RED AND BLUE COLOMBIAN TETRA (Hyphessobrycon columbianus) ENJOY YOUR EXPERIENCE? LEAVE A REVIEW HERE.
