Yeah, like Thekid said, rummynose are very peaceful but they are very active, always moving. They all hang together closely, too - more so than some others like say cardinals - so I'd get a big group of 10 or more for sure.
In my school, I have a couple of big fatties and they are maybe 2 inches. The biggest ones are more of a fatter shape overall than the smaller ones, rather than all that much longer, if that makes sense.
