tword op, all the advice was excellent you should really take it and use it, there is no less is more with burms what are u gonna feed a 12 foot snake in? and then how are u gonna move it when it still wants to eat for the next 6 hours? my 6ft retic stays in feeding mode for a good 8-12 hours after eating and i couldent imagine touching him simply due to the danger
also i feel u have some seriously wrong info when it comes to burms period, a 6x2 isnt big enough for a female, thats a males size enclosure and alittle on the small side for that. trust me spend the money now and enjoy them at diffrent times very few people can appropriatly house multiple snakes together.. it CAN be done iv seen and read it but it was NEVER done for your reasons... EVER the people who do it have been working with reptiles for years and know their animals and dont simply try to save space or money..
i also noticed u get defencive when money is brought up, bud u didnt get two hamsters your talking 10-15 feet snakes here in the first 2 years there is no skimping theres minimal like racks and what not but u need to be able to support both (which u say u can) so i highly reccommend two diffrent enclosures for the welfare of the animals which u say u care about
