I agree, a 10 gallon is goos for juveniles but not for adults. A 20 gallon is the minimum, but a 20 gallon long is perfect.
Just a couple things i would like to add:
1- vary the diet. use silkworms, butterworms, and for adults, super worms, goliath worms, and hte ocasionnal pikny mouse.
2-you shouldnt house a make and female together because excessive breeding will stress the female. just introduce her once and she will have enough sperm to go through the breeding season.
but overall its a good basic caresheet, just a bit more info is needed and some corrections to be made.
