No not a pair. Just the last two left at the time
Ah, then my guess would be two females. Wild-type
A. cacatuoides females don't show much color in the fins, but the 'Super Red' line does. You should keep an eye out for a male! Male and female shown here-
When the 'Super Red' line of
A. cacatuoides first started to appear in the hobby, the vast majority of fishes available were males, presumably because breeders were attempting to minimize competition from hobbyists by making female breeders difficult to acquire. This wasn't difficult to do, as the sex ratio of
A. cacatuoides broods, like many
Apistogramma, is strongly dependent on pH and temperature. Temperatures below ~78°F result in a preponderance of females; above that, a preponderance of males. My guess is that this situation no longer holds, but in any event, it shouldn't be difficult to find a male. You could also get an 'attempted pair' from the Wet Spot; one male with three females in a 46 would be a nice combination.
