I keep them in Pine and screen racks in Zellers "Truly" brand sweater box trays(similar to Rubbermaids but cheaper and slightly wider)
There should be lots of info on the web. try googling for spotteds as well. Spotteds are almost the same snake so any info on them will be suitable for childreni. Only a few years back they were all considered the same thing anyway.

I keep them all in these type systems(above)
and below are few more pics in these trays

photo above is a couple of striped spotteds. there is two of them in photo but only for the picture
