They'll be fine in that tank while you grow them out a little. Just be sure to do frequent water changes and filter the gravel really well.
I had Shubunkins (and butterfly Koi) in my ornamental pond for a long time. Most of them were a good 8-10" before my neighbors cats wiped them out. I'd had them for almost 7 years
