Aphyosemion Bivittatum/Australe - egg production

[Magnos]

So I have 3 species of aphyosemion. I am getting conflicted information online. I have all three at around 78 degrees. Super soft RO water at 5.5 PH. Volcanum, Bivittatum, Australe.
I have been getting around 5 eggs every 3 days from A. VOLCANUM. - 78-5.5 PH
From australe I've gotten like 4 eggs over 2 months. - Originally had the temp at 78 but lowered it to 74 after some online digging. I'm still not seeing the eggs production I should be. Any insight? Having a similar issue with Bivittatum.

How old are the fish? What is the spawning medium and where in the tank is it located, i.e top or bottom? Pairs? Trios? Did the eggs hatch? My killies (Aphyosemion and Fundulopanchax) are kept cooler, 68F to 72F or so and produce well.

That's far too warm. I have been to the habitat of australe, for example, although we didn't catch any at the end of the dry season. The water was 22c, which google tells me is 71.6f.

Answers to @Innesfan's questions will help, and I'll add. I find what they eat crucial. So what is the diet. How often do you feed them.

At your temps, they will die very young. They aren't annuals, but that'll give them a short life.\

I confess, I have never found australe easy to breed, in spite of their reputation. But the two Chromaphyosemions should be quite easy to get a lot of eggs from.

I'm still keeping the Australes. And I keep them at approx. 20°C (roughly 68°F). Haven't had any reproduction problems. I had other killifish before but in some way I like the Australes best...

Copy that thanks guys dropping temps now. Feeding a rotation of BBS frozen spirulina blood worms and high quality pellets

I have two young pair of a. "funge" I am conditioning to spawn. I keep reading they do best in temps of 78F. Do you think they should be kept and bred in cooler water or ar they different from what you keep?

I kept and bred bivittatum Funge for about 5 years in the early 2000s. I never heated their tanks, and found they did poorly at summer temperatures like 78f. I bred mine at 23c/73.5f. They were very productive and I distributed a lot of pairs locally- I also had a bivittatum from the Cross River region that I kept and bred the same way.

They like warmer temperatures than a lot of Aphyosemion, and warmer than a lot of their fellow Chromaphyosemion. But 78f seems very high to me. I found that in winter at around 19c, they barely bred, and would only breed them in Spring and Fall. In high summer where temps could get to 28-30c (in the 80sf), they also shut down. They sure made up for it in season.

Like a lot of killies, they took some types of flake, but egg production was barely measurable if I fed those processed foods.

I prefer their close neighbour biteniatum, and when I encountered space problems, kept the bit and sold the bivs.

Thanks for the info! I will drop them down a bit.
