Fundulopanchax is a genus of killifish living in near-coastal fresh water streams and lakes in Western Africa. All species were previously biologically classified as members of the genus Aphyosemion, with the exception of Fundulopanchax avichang, F. gresensi and F. kamdemi, which were all scientifically described after the major revision of the Aphyosemion complex. The name Fundulopanchax is composed of the names of two other genera of killifish, Fundulus Lacépède (1803) and Panchax Valenciennes (1846), which were previously wrongly thought to be closely related to each other. Bellow is a button linked to an excel file with accurate Fundulopanchax species keeping and breeding data.
Please note the following:
- If maintained at higher temperatures Fundulopanchax species became susceptible to disease & aged faster.
- The incubation time varies depending on the incubating temperature, lower temperature – longer incubation time and vice versa.
- Fundulopanchax species are susceptible to Oodinium (Velvet) disease (concentration of salt in the water will eliminate 90% – 95% of the health problems). Add 1 (one) teaspoon of marine salt per 4 litre of water for both – adults and fry.
- Sexual maturity and life span depends on food and keeping conditions.
- Adding dead leaves (Oak, Beech) act as an anti-bacterial and anti-fungal agent, and also lower the heavy metal content of the water.
- It is widely accepted that it acts as a spawning trigger and can aid in the recovery of any fish damaged through stress or fighting.
- Please note that a solid leaf litter is an integral part of most Fundulopanchax biotopes.
- It is recommended using a small, air-driven sponge filter to prevent water stagnation.
- The aquarium should be moderately illuminated. Always use floating plants to reduce open-surface / light stress.
- The fish should be conditioned on a varied diet of live foods.
- For breeding keep the two sexes apart in separate conditioning tanks and select the best male and plumpest females, before placing them in the spawning tank. This method allows females to recover between spawning sessions. Each pair or trio should only be allowed to spawn for a week or so before being returned to the conditioning tank. The spawning process is hard on the fish (particularly the females) and they can become fatigued and weak if left for too long.
- Species with long peat incubation times (more than 8 weeks) require egg re-wetting several times as for annual killifish.
- Extreme care must be taken regarding water quality in the fry raising tank.
- The fry should be fed twice a day with small water changes every 2 – 3 days for the best growth. Larger fish should be moved on to another tank as they can eat smaller fry.
- Some species may have resting periods when no eggs are laid. Lowering water temperature may work as a trigger for spawning. For species with very long peat incubation times (more than 12 weeks) lowering the water level may work as a trigger (beginning of the dry season) to lay eggs.
- Egg sizes are approximate. In most cases they are reticulated, adhesive and difficult to find in peat.
