Best thing is to get a plastic solo cup, poke tiny holes in it, small enough he can't squeeze out.
Place a bit of indian almond leaf or moss inside the cup with the fry.
Keep the water aerated, airstone outside of the cup. But keep the water just a few inches deep.
So for water changes, you just siphon out the water outside of the cup, so you don't siphon up the fry. Water changes are best daily
And in the cup, he can get food easiest (yes first bites is fine for him).
At least at a week old, add a very thin layer of sand--substrate is necessary as it holds beneficial bacteria and prevents infection and fry loss.
I'll get you a photo of my set up right now...
