I bought the only matching pair of wiesbaden swordtails from a local fish shop and as usual they were in a tank with other mixed swordtails. The Wiesbaden strain was first developed back in 19 37. Many of the color varieties seen today are descended / re developed strains from the past. When it comes to cultivated fish it may be easy to pick out what seems to be a matching pair both fish may be genetically different. And of course there’s the risk of them being impregnated by a different color variety. However, by selective breeding it is possible to get these fish to breed true,
