Fundulopanchax gardneri gardneri
It is possible to keep these killies in a community tank with other fish of similar size or larger, but not with long-finned fish as these will be shredded! Males will happily start their own Fight Club.
Fish information (behaviour and breeding):
They will reach a size of up to 8 cm, but will breed at half this size. They will accept most foods apart from low quality flake, and they prefer live or frozen foods. Ideal water conditions are soft, slightly acid to neutral water (pH 6.5 - 7.0) with a temperature between 72 and 80ºF. To achieve breeding success, a male with 1 - 2 females in a small, well furnished tank with soft, slightly acid water between 74 and 80ºF should generate results. They will spawn in fine leaved plants or breeding mops, in a soft substrate such as peat. The fry will take newly hatched brine shrimp on hatching. Eggs can be found at all levels of breeding mops and among fibres of peat substrata if provided and are like tiny glass beeds about 1.5 mm in diameter. It's best to move the eggs on breeding mops to a seperate tank or container with about 5 cm depth of water from the parents' tank in which to hatch in case the adults get peckish between meals. The fry will hatch in 14 to 21 days. If the eggs are spawned in peat, this can be removed from the tank, squeezed to release most of the water, left until just damp and stored for about 8 weeks in a plastic bag or container. At the end of this period drop the peat in a tank as described for the breeding mops and the fry should hatch out within 48 hours. This simulates the natural drying out of some streams and pools in the dry seasons, where the eggs survive the drought and are triggered into hatching when the rains return and refill the waterways. Fish that use this optional breeding style are called switch spawners.
There are 3 subspecies of this fish (which was known as Aphyosemion gardneri until quite recently) - gardneri gardneri from Nigeria, and
the less commonly seen gardneri lacustris from Cameroon and gardneri mamfensis from both countries. The colouring varies considerably amongst the males, not only between the subspecies, but the regional variations as well.
The females are fairly similar in appearance, having shorter, more rounded, almost colourless fins and sandy brown to greyish brown bodies with red dots on their flanks.You must have either 1 male with 1 or 2 females, or a group of 3 or more pairs to soften the violence between males. Keep the aquarium well covered as adult fish can leap several inches out of the water.
