placing 4 month and 9 month old SI together

[gotham229]

So I have two 4 month old SI and 3 ,9 month old SI. The 9 month old ones have been together for about 4 months. There seems to be 2 males and a fat (probable) female. I recently acquired some 4 month old SI. Two of them have patterns that I like. I was wondering if I could place all of them together in a 20H. None of of the frogs are in the 20 yet. There is a lot of cover for all of them to hide in , especially leaf litter. I was thinking about maybe putting the younger ones in first then the older ones. PLease let me know. Thank You very much.

Normally adding all of the frogs intended to be in a tank at the same time is ideal. A single 20gal for 5 SI's would be pushing it in my opinion. Now a little larger tank, then maybe.
