I have had them for about 2 weeks they are 1.5 inches from head to tail kinda small guys but I read an article that said they start young. They seem paired off already, check out this pic they are next to each other.
They say the male will turn really black, well he does that from time to time but it doesn't stay that way.
HELP!
