I might want to put a male and female guppy in a 20, hoping the female gets pregnant. I will put her in a breeding box when she is close to giving birth. Could I then feed them to my juvenile JD.

I raise my own for my cichlids. The 20 is the perfect size for the guppies, mine are in a 20 long and are doing great. I wouldn't get a breeder box, it can stress the females too much and can give them problems while dropping the fry. Just get a simple air pump powered sponge filter, that way the fry can't get sucked in. I'm running one and my regular filter is also in there with a net over the intakes.

Also, to produce enough guppy fry you should get 1 male per 2 or 3 females. This will reduce aggression from the males as well, they can stress a female from too much mating. I have about 30 in mine, waiting for the second generation to start pumping out babies too before I start feeding the cichlids again. Also, most likely the females will be pregnant at the store so you may get a ton of fry quickly. They drop a bunch every month, and in order to get them to be a good size for your JD I would wait at least 2 months for the fry to get big enough. Feed them 3-5 times per day with a good diet high in protein and veggie matter and they will grow fast and be super healthy compared to the feeders at the fish store. Live plants will also be a great addition to the tank. Get floaters like hornwort and anacharis, they will protect the fry, I've seen guppies occasionally eat their own babies.

Remember the guppies should only be a treat maybe once a week, your JD will still need a regular diet. :D
 
Yes, and I believe that JD's are found in Mexico alongside swordtails and other live bearers - so you would be re-creating their natural diet a little bit. But as said above - you should have a quality pellet food as a staple and give the feeders as a treat. Even in the wild I doubt a JD's diet is 100% fish. They probably eat insects, snails, worms - whatever they can catch...
 
If you like feeding fish to fish- if that's your thing go for it I guess. You won't produce enough fry in a 20 to produce anything but a VERY quick snack. I grow mine in a pond during the spring and summer and it's still a drop in the bucket. My adult JD could make a swarm of 100's of fry disappear overnight. She can eat probably 6 adults in an hour if I let her and kill the rest before they can breed. I have attempted to breed live bearers to feed to my fish and very quickly decided it was a waste of time. Perhaps in a 90 gallon or more you might be able to pull it off with swordtails or mollies but in a smaller space they will not out breed your fishes appetites.
 
In nature live bearer fry seem to be a normal part of a JDs diet, and it helps control the population of the live bearers, and weed out the weak. But I have watched them miss normally 9 out of ten times, that probably wouldn't happen in a tank.
