Waiting to hear those measurements, since the difference between a M and L of the RBIs is big, don't think my 800gish male can fit in a M but not sure how I'm gonna get two L's in his enclosure.
These makeshift green ones aren't gonna last much longer so I gotta look into other options soon and the local exotics store only has one M available until some indefinite point in the future. But don't want to buy M's online and find they're far too small and then have to go through the pain of returning them. Sigh.
