I've been raising and breeding guppies for about 4 years now, just as a hobby.
As part of that hobby, I've been doing a "selective breeding program" by maintaining 3 different tanks for the guppies.
Tank 1: The "mama" tank. Here's where my breeding stock females go. This is a regular 10 gal tank with a standard flip lid with easy access to the top, for easy scooping. Floating on the top of the water in this tank is two "baby havens" - green plasty plant-like things that have a flat bottom and shallow, bushy fronds that I float upside-down.
Tank 2: The "Adult" tank. The non-breeding females and all adult males go.
Tank 3: The "baby" tank.
When I want to breed for a specific trait, color, or whatever, I just put the male in the mama tank and let nature take its course. Every morning, and throughout the day as I think about it (or my husband, either one of us), we stop by and check the mama tank for babies and scoop them out with a brine shrimp net and put them over in the baby tank.
With the 2 floating baby-savers, a crockery pot in one corner and a rock cave in the other, the babies have plenty of places to hide in the mama tank after they are born, and the ones that are eaten by the other females - oh well. That's natural selection for you. At the rate they breed, if I didn't have SOME form of culling in place, I'd be very quickly overrun with guppies even more so than I already am, so it's not big deal.
Every so often, as I want more "fresh blood" or find a cool new strain at the lfs, I get new males and put them into the mama tank. I almost never buy females, since it's easier to buy a male and let them do their thing with the females.
I would say that things have been pretty successful so far. I've bred for some amazingly large fins and tails on the males, mostly in the black tuxedo strains, but some gold tuxedos. I also did some color matching, starting out with some red blondes and a Japanese Gold, then adding a yellow delta to the mix several generations later, and most recently adding a Tequila Sunrise to the mix.
I think my most interesting result to date, however, was what I call my "American" guppy - a Red, White & Blue colored guppy strain that came out of the Red Blonde, Japanese Gold and a Russian Blue.
So does anyone else have any experiences, stories, anecdotes or fun facts to share about breeding guppies? Advice? Questions? Complaints?
