This guy is one of the baby you DID NOT suck out of the mother Gig right? The only one?
How big is he in actual size. Diameter of 1/6,1/4, or 1/2 inch?
Now that he can eat, I am sure you can raise him really quickly.
I can think up of multiple ways to set up a tank that will have adequate circulation but safe for the babies. Hopefully so they won't get chewed up by circulation.
I actually see the pod next to it. I guess about 1/4 inch diameter. He will be fine.
