Mine haven't changed colours at all. Well, in the beginning they weren't as bright as they were on the site, but then after a couple of months they went bright again. The one available now isn't as bright as mine were, so I don't know how bright it will go. I took some new pics last night, but I'm on my way to work and will post some tomorrow.
I really REALLY like these guys. We may have a male and female but are also not sure if it's just a juvie variant because one is very small.
