My juvies from Ken Davis are growing out nicely. I bought two Carpinitis, one is close to 3" with the other around 2 1/2". The face of the larger of the two has developed this black coloring. Only way I could describe it, is it looks like he/she's got a 5 o'clock shadow. He/she has been like this for 2 weeks. I've never had these guys so I'm not sure if it's a normal dominance thing since the smaller of the two doesn't have it. I know a pic would be great but my camera died on me so I can't post any right now which really sucks. Anyone have any suggestions?
