Woma pythons (Aspidites ramsayi) are excellent snakes to keep - hardy, voracious feeders that are relatively easy to breed.
I keep mine set up in appropriately-sized caging (shoeboxes for babies, sweaterboxes for juvies, Freedom Breeder "2 across" rack for adults), with aspen substrate, a couple of hide boxes, and a water bowl. Ambient temp ranges from 75 - 85, with a 90 degree hotspot for juvies/adults (it's hard to create that kind of thermal gradient in a baby box).
Feeding - once a week is fine, although they will most likely eat anytime food is offered...I feed my juvies/subadults 2x week for the first year or so & then back them down to weekly feedings after that point. Womas tend to have VORACIOUS feeding responses - watch your hands when the cage opens. They rarely tend to be picky feeders & are very easy to maintain on rodents.
Handling - most womas are very docile, active, inquisitive pythons. Babies may be nippy or shy at first, but the same is true for many snake species. Some womas may always be defensive & not take well to handling, but that is more the exception than the rule.
The main reason womas haven't been a widespread "pet" snake is due to the price. Not many folks are willing to pay $400 - $1200 per animal when there are so many cheaper species out there.
Also, a note in regards to subspecies - there aren't any subspecies at this time that have been clearly defined, published & widely accepted. Proposed subspecific designation pops up from time to time, usually from various sources looking to make a name for themselves, but that's the extent of it at this time.
HTH!
