When they are this faded they could really surprise you when they come back. They might completely change colors on you I have picked up a wild colony from Vietnam and they were all completely brown with no color so the guy let me have it for around 10 bucks...Two weeks later they looked like this...
its the cology on the right which now look bluish I placed them with some radioactive dragons but I still dont have a name on them and some bambams below
