Breeding the Congo Tetra

You will have a bigger breeding tank than for many tetras due to the scale of the breeders and since they’ll produce 300 or extra eggs (all are almost certainly to hatch). The college of fry will develop quickly to a dimension bigger than full-grown neon tetras in 4 or 5 weeks.

Use a 15- or 20-gallon lengthy tank on your breeding venture—10-gallon tanks aren’t advisable. Boil sufficient peat moss to cowl the underside of the tank with 1 inch of loosely packed moss substrate (about 1/2 cubic foot for a 20-gallon lengthy tank). Add it to a tank already stuffed with reverse osmosis, distilled, or rainwater if in a rural space, and let it sit for just a few days till the peat moss has fully settled. This may present an atmosphere with delicate, acidic water.

Place a number of thickets of Java moss on prime of the peat moss substrate in a number of areas. Present extra nylon breeding mops or a number of clumps of fine-leaved vegetation. The water temperature ought to be a gradual 77 F. There ought to be no aeration or filtration since this could disturb the peat moss and cloud the water.

Place a well-conditioned pair of Congo tetras that has been stored in separate tanks for a short while to arrange for breeding into the breeding tank shortly earlier than lights out or shortly earlier than sundown. Most pairs will spawn the next morning, or when the lights are turned again on. Darkness ought to be maintained for no less than eight hours to stimulate spawning.

This differs sharply from their South American relations, whose eggs hatch a lot faster, however whose fry dangle on vegetation for a number of days, being smaller and extra helpless at first. When Congo tetra fry seem from the peat substrate, they’re absolutely free-swimming and hungry.

Congo tetra fry could be fed infusoria for a day or two earlier than they’ll take child brine shrimp. They are going to develop shortly and take powdered dry meals inside two weeks, quickly reaching nearly 1 inch in size.
