I vaguely remember reading about these when I researched my spotted python, & by the way, she's only about a foot longer than the 28" Anthill pythons,
and they look very similar. (my "Spotted" is a granite phase) I checked out the link you posted, I can't imagine keeping a 28" snake in a 10 gal. for life, but
maybe a 20 gal.? My Spotted (10 years old, so she's fully grown) is quite comfortable in a 30 gal. tank. The Anthills are pretty tiny as hatchlings & even the
Spotteds can be tricky to start off (their first food in the wild is lizards, then as they grow they get bold enough to take small rodents) so you might want to
make sure you get a well-started one, if you go ahead.
