3) tooth cusps in the inner premaxillary row arranged in a straight row (vs. savagei) the middle teeth in the inner premaxillary row with five (to seven?) cusps (vs. savagei Bussing, 1967 but differs in a number of characters as follows: possession of a significantly deeper body measuring 47.4-50.7 % SL (vs. Within the genus it appears to be most closely related to the Costa Rican endemic H. ecuadorensis for several years prior to its description. This species is also traded as ‘blue flame’, ‘blue-red’, and ‘Colombian red fin’ tetra, and was misidentified as H. Initial food should be Paramecium or a proprietary dry food of sufficiently small (5-50 micron) grade, introducing Artemia nauplii, microworm, etc., once the fry are large enough to accept them. Spawning normally occurs for 2-4 hours and a well-conditioned mature female may lay as many as 2000 eggs during this period, these normally hatching in 24-36 hours at which point the fry still have a good-sized yolk sac attached. When the adult fish are well-conditioned a single pair or group comprising one or two males and several females can then be introduced to each container and left in place until eggs are detected (typically the following morning). The water itself should be of slightly acidic to neutral pH with a temperature within the range suggested above.Īn air-powered sponge filter or air stone(s) should also be included to provide oxygenation and water movement. or spawning mops can also return decent results. The widely available plastic ‘grass’- type matting can also be used and works well, as does a layer of glass marbles.Īlternatively filling much of the tank with a fine-leaved plant such as Taxiphyllum spp. This should be very dimly lit and the base covered with some kind of mesh of a large enough grade so that the eggs can fall through but small enough so that the adults cannot reach them. The adult group can still be conditioned together but a smaller aquarium should also be set up and filled with mature water. However if you want to maximise yield a more controlled approach is required. When in good condition adults will spawn often and in a mature aquarium it’s possible that small numbers of fry may start to appear without intervention. ReproductionĪn egg-scattering free spawner exhibiting no parental care. Sexually mature males are noticeably more intensely-coloured, slimmer-bodied, a little smaller and develop a more-extended dorsal-fin than females. Try to buy a mixed-sex group of at least 8-10 specimens, include other schooling fishes to provide security, and you’ll be rewarded with a more natural-looking spectacle. It’s perhaps best-maintained alongside similarly-sized characids and relatives, smaller callichthyid or loricariid catfishes and non-predatory, medium-sized cichlids.

This species does best with soft slightly acidic water with high filtration.Ĭolumbian Tetras will breed occasionally in an aquarium setting and a hospital or "breeding tank" will be necessary. Rocks and driftwood help mirror its natural habitat and will help to reduce stress on this fish.
