Hi guys, I have a pied female that's 7 mos old, weighs 510 grams that is in a 20 gallon long reptile tank. She now gets a small rat every 3-4 days with gusto , great feeder . Just wondering at what age/weight can I transfer her to a 40 gallon reptile breeder tank without getting all stressed out so I can use that tank for my female BEL that is currently in a 10 gal tank , 3 mos old , weighs 185 grams , takes a f/t rat pup every 3-4 days . I also have an 8 yr old albino female that weighs 2000 grams , 4.5 feet long currently in a 40 gal reptile breeder tank. Thanks for the advice .
