Is there any risk of interbreeding with these two (or other) species of Victorians? I'm just getting back into the hobby after a long absence from the country and the Vics have always been my favorites. I'd love to put together a very large Vic community tank, but I'm concerned about hybridization. I feel that it is our responsibility as the keepers of endangered fish to produce viable offspring only, so as to keep the species strong. Is it doable? Could I only put certain species together, say, if they were all of a different genus?
Excellent question!
In most Victorian species, the silver coloration is similar in all of the females. The reason I have Xystichromis sp. "Kyoga Flamebacks" mixed with Paralabidochromis chromogynos is that while the "Flamebacks" do have females with the standard silver coloration, the Chromogynos are piebald, both male and female.
I will say that over the long term, I don't believe this particular mix is going to work; not because of hybridization issues, but because the male P. Chromogynos is very aggressive, and will take over a large portion of the tank. This is keeping the "Kyoga Flamebacks" in check, and mostly in hiding.
I do suggest species tanks for Victorians. They can hybridize fairly easily, given that the females look so similar.
