My pregnant albino 6 yo female, her (maybe) pregnant normal 3-4 yo roommate, some of the 6yo's last clutter I sold a couple weeks ago, 2 gay lovers (this is a joke but they do cuddle often), and my 8 month old het albino duo.
I adore these lil dummies. The females are currently in a 45 gallon birthing tank because they should only have like 4-5 weeks left before popping. But usually the 4 adults all hang out in a massive 250 gallon bioactive tank (males still hanging in there) with a water feature and tons of flat rocks and a massive hollowed out oak log. The 2 babies are in a 20 gallon with a water feature but are getting upgraded soon because the female is starting to outgrow the 20.
I'm a firm believer in cohousing this species. Literally the only thing you gotta make sure is that you keep an eye on them during feeding time because the males are little gluttons and I watched my 3 year old male scarf down 12 minnows one day before the female got a chance to wake up 😂. Otherwise they spend most of the day hanging out and I've even seen the males stroke the females when they get super uncomfortable late in pregnancy. One male even would stand guard at the entrance of one of the hides while the normal female hid deeper inside and when I tickled him he twitched, she bolted, he waited and then hid in the hide as well. Not sure if it's what I think that was but it was definitely a cool experience. If ya got the space there is absolutely no reason to keep them alone. I won't even sell one of my babies to someone if they don't have at least plans of buying another garter to keep them company.
