THE FISH
Killifish (F. filamentosus)
Fundulopanchax filamentosus
| HABITS |
|
Coming from Benin, Nigeria, and Togo, this species can be kept with other fish of a similar size, provided that they are not slow or long-finned, as the males can become aggressive. Water conditions should be soft and slightly acidic (pH 5.8 - 6.8) with temperatures between 70ºF and 76ºF. These fish are capable jumpers, so be sure to have your lid on securely.

| BREEDING |
|
It is possible to breed this fish using mops, but the best results are obtained when they spawn in a soft substrata, such as peat, which should be boiled to sterilise it and reduce its buoyancy. A pair or trio (1 male and 2 females) should be placed in a well-furnished 2-3 gallon tank. For easy removal, the peat should be introduced in a plastic container at a depth of 1-2 cm. After about 3 weeks, the container should be removed and replaced with new peat. The peat containing the eggs, which are approximately 1 mm in diameter, should be gently squeezed to release most of the water, left damp, and stored in a closed plastic bag for about 6 weeks. At the end of this period the eggs should be put in a tank containing 2 cm water from the parents' tank. If the fry are ready to hatch, they should emerge within 24 hours and will feed on microworm moving on to freshly hatched brine shrimp after a couple of days.
