![]() In their natural habitat, Colombian Tetras are omnivores that feed on insects, worms, zoo-plankton, organic detritus, and small bits of plant material. When the yolk sacs are absorbed, the fry should be fed infusoria or finely crushed flake food until they are large enough to accept microworms, Daphnia, or newly hatched baby brine shrimp. Like most egg scatterers, the parents or spawning group should be removed from the breeding tank after spawning is completed or the eggs will be eaten.ĭepending on the water temperature, the eggs will hatch in 24 to 36 hours. ![]() Spawning activity usually lasts anywhere from 2 to 4 hours and as many as 2000 eggs may be laid. When a well conditioned group of one or two males and several females are introduced to the breeding tank, eggs will normally be observed the following morning. and fitted with a seeded sponge filter or air stone to oxygenate the water and provide some water movement. Regardless of what you use, the breeding tank should be filled with slightly acidic water with a pH at the lower range of 5.0 – 7.5, a temperature between 70 and 82 degrees F. A less efficient but more natural media is a carpet of Dwarf Hairgrass or a bed of Java Moss on the bottom of an aged tank. Many breeders use a commercially produced plastic grass like matting or a layer of marbles to cover the entire bottom of the tank. To maximize the amount of fry that are produced, place a well conditioned adult group in a small dimly lit tank filled with aged water and a fine mesh carpet over the bottom that is large enough for the eggs to fall through, yet small enough so the adults cannot access the eggs. In a mature aquarium, they will often spawn spontaneously without intervention and occasionally a few fry can be observed. Like many tetras, they are egg scatterers that exhibit no parental care after spawning. They should be housed with at least 8 to 12 of their own kind and get along well with other like sized schooling tetras.Ĭolombian tetras do best in a 30 gallon aquarium with a fine gravel substrate that is densely planted with fine leaved plants, some driftwood, moderate filtration, a slight degree of water movement, and plenty of swimming space. Sexually mature males are slightly smaller, more intensely colored, and develop a more extended dorsal fin than the females.Ĭolombian Tetras are a peaceful shoaling species that make ideal residents in a South American community aquarium. The caudal and anal fins are a bright blood red color and the ventral fins are transparent to a light orange color. Originally misidentified as Hyphessobrycon ecuadorensis, the Colombian Tetra has a deep body that is silver colored with iridescent blue on the back and upper portion in both males and females. The fins are red in colour, the caudal fin being the most vibrant.Colombian Tetra (Hyphessobrycon columbianus) Pair It's body is pale in colour with vivid blue/green iridescence. Identification An attractive little tetra, a high-backed tetra with Piranha-like visible teeth. Some hiding places in plants would be appreciated.īehaviour A peaceful shoaling fish that may fin-nip longer-finned fish if not kept in a reasonable sized shoal. ![]() Will happily co-exist with equally active robust fish, but do not keep with long-finned, slow-moving or shy fish as the Columbian Tetra is very likely to fin-nip.ĭiet Omnivorous, will take pellets and flake as well as live and frozen food.įeeding regime Feed once or twice a day.Įnvironment specifics This fish prefers a spacious tank with open swimming place and room to shoal. Tank compatibility An active community fish that should be kept in shoals of 6 or more. Sexing Males are more brightly coloured with slightly more elongated and elaborate fins, especially the dorsal fin. Additional names Columbian Tetra, Blue Flame Tetra
