Interesting. If I get access to them again, I'll try them in smaller tanks. It's possible that one or two aggressive pairs coloured my view of how to keep them. It's a good fish, well worth any space.
Pity can't walk across the border grab a few and then walk back with them - i know nothing about canada and availability but in usa they are mostly readiliy available if you don't want to travel to africa and collect them yourself.Enigmatochromis are an enigma. As a very energetic crow would fly, they are over 2000km/1200 miles from where P pulcher, the krib, occurs. Between the 2 species, there is a wide range of related Wallaceochromis, but almost no Pelvicachromis except for the weird and isolated P roloffi. You can see the relationship with the colours, but the body shape is very different from kribs. Look at their heads.
In that region, there is a large group of killies that look like the Aphyosemions farther south, and used to be considered as part of that group from the eyeball test. It turns out the relationship isn't close, even if the appearance is. The northern Scriptaphyosemion types are more closely related to Epiplatys pike killies then to their lookalike southern more distant than we thought cousins. They come from a different evolutionary pathway.
This is cool, but may matter if the same sort of thing happened with the Cichlids of the broad region. I may just be amusing myself wondering about that.
I'm now officially on the hunt for Enigmas. I seem to be getting into dwarf Cichlids again. The hunt for them, for Nanochromis, Congochromis, Pelvicachromis, Benitochromis, Parananochromis, Steatocranus - there is no shortage of possibilities, even if there is a shortage of actual fish available in my small population country.
