Black Moscow Guppy (Pair)
The coveted Black Moscow guppy has an interesting history. The half-black guppy was developed in East Berlin in the late 1960s. Quite a bit of breeding was done behind the Iron Curtain since it was very difficult – impossible actually – to import new varieties. That is one reason that even today many amazing killies, cichlids, guppies, and apistogrammas come from Central European breeders. Russian breeders took the half-black variety and were able to produce a full black male – very striking. These fish are still tough to breed but well worth the effort! Females have a little silver on the body, and not all offspring are full black; most, in fact, are half-black. Each order comes with one male and one female.

Received the pair as described. The male is striking with solid black color and the female has a nice silver sheen. They seem healthy and active in the tank. A bit of patience is needed for breeding, but the coloration is worth it.

The fish arrived quickly and looked vibrant. The male is very bold and the female is calm. I’ve noticed some of the fry are half-black, which matches the description. Not easy to breed, but the result is beautiful.
