Looking to get a few gars but with all the caging out there and all the caresheets everything is different. Whats a good sized cage for 2? maybe 3? I hear its better to house a male and female vs female female and male(true?) Also they need humidity so are them screen cages any good for them? We normally make our own cages but curious as to if there any good for gars. Also any little tips would be great;D
