Aphyosemion Volcanum

[Magnos]

I have about 15 fry now.
Feeding live bbs twice a day. And frozen food once a day. My gardneri spawned in a mop and in a deli cup of peat moss. I tried it with this species and I got 0 eggs.
I've tried a bottom mop and floating mop.
The floating mop always has more eggs

The Chromaphyosemion group are great. I kept a volcanum population for close to 10 years. They always spawned in floating mops, in the top few inches.
But C. poliaki, which I keep still and which are from cooler, higher elevation waters in the same region, spawn all through the mop, and sometimes in gravel.
My Chromaphyosemion biteniatum eggs can't even be collected. If I touch them, they die. But I have had the species since 2005, with young showing up in planted tanks.
With killies, every species has to be explored as an individual unit of life. There's no one trick that works for all.

I haven't even known about chromIChromaphyosemion. First time I'm even hearing it lol

US fishkeepers seem not to accept the revision, but the 2 striped Aphyosemions are now Chromaphyosemion.

Well really! Lol I have volcanum and bivittatum they both have 2 stripes. They are cheomaphyosemion now?

Yes, as @GaryE stated there's a split in the killie world about this. The subgenus Chromaphyosemion has been around since 1971 but in some parts of the world, it has been elevated to full genus status. This is from Jean Huber's Killi-data site. It's interesting since Huber, a killie authority of the highest order, is French, but leans toward the American view on this.

"RESEARCH: Chromaphyosemion

Status evaluation (current): established by several authors {also seen as a full genus, but no significant diagnosis yet forwarded, and latest evidence by Huber, 2013, seems to push for subgenus status}.

Systematic remarks (with taxonomic history and changes in edition since 2001): well defined (taxonomic history : variably considered according to authors, either as a subgenus of Aphyosemion or as a full distinct genus, the former option being retained because it matches the latest published evidence by Amiet, 1987, Agnèse et al., 2006, Huber, 2013, with various methodologies)."

Regardless, it's a lovely group of species well deserving their popularity.

Because I can't get my killies from the USA, and haven't been able to for many years, I kind of fall into the European usage. I am not qualified to decide on the differences. If I look for eggs or species trades, I talk with European people in the 'Chromaphyosemion' camp, and since it does make sense, I roll with it.

It's like spelling - I'll spell American to Americans, and Canadian to the rest of the world.
