Breeding A. Congicum

Breeding A. congicum
by Monty Lehmann

A. congicum (or the old name of A. melanopterum)is a little harder to breed than some killies because it is fussy about its water conditions. You probably started getting eggs because your water became more acid from not being changed for so long. Congicum likes acid water, around 6.0. I add peat moss to a box filter to bring my water ph down, but you must monitor the water conditions a little more than other species as dirty water is not tolerated well by congicum.

I never had any fry grow up in my breeding tanks, but they only had several large mops in them, no plants. So, I would say that they are fry munchers.

A. congicum only has one other requirement for successful breeding: live foods for the adults and infusoria for the fry (for the first two weeks at least). The eggs are tiny, but I handle them like any other Aphyosemion until they hatch. I suspect that a rotifer culture would serve well as fry food for congicum.

A note about water changes: Unlike many of my other Aphyosemions, many of whom produce a burst of eggs after a water change, congicum would nearly always turn off ( stop laying eggs) for up to seven days after a water change. Perhaps a shift in the ph until the peat moss could release more tannins? I never investigated this change of mode as they always started producing eggs again.
