I would say that ONE JD "should" be OK in a 29g until May, but you are moving him, then moving him again and there will be water quality differences twice in a short time.
I had a problem with an Oscar and a JD in a 55g - the JD picked on the Oscar constantly when they got to be about 5".
Look at the JD fish profile and figure out what size tank for a breeding pair. No shame in a Petsmart fish as my JD and Oscar came from there and were both unusually beautiful when they grew some.
