Definitely move the fry. A heavy plastic bag that won't fold back on itself, like some of the heavier ziplocks, shaped and hot glued to an old net frame, works well for fry once their siphoned out of the main tank, and for stragglers that seem to avoid the siphon. How many of these babies are ya lookin to raise to a tradeable size? If you're goin' for all of 'em, then you'll need a 55 with every other day water changes to maximize growth. Otherwise, a twenty if you're only lookin' to end up with 6-12 of the best and healthiest. I've used 10 gallon tanks for growout but ya have to be ready to cull regularly to keep 'em growin' well, and then ya risk the chance of cullin' some potentially nice lookin' fish. Cull for shape as well as size, or ya might end up with a lot of excess males, LOL, and cull any with obvious health problems. Your jag should be well fed for a while.

Edit: Guess I shoulda read closer, Ddawg already covered most of this, LOL.
