I have 10 yellow calvus. I have had them since October and they are finally getting some size to them.
7 of them have colored up yellow but I have three that have remained dark like they did when I first got them. Now these three hang out by the dark colored rocks I have while the other 7 hang out around the shells and the white sand.
So the question basically is are these three dark because of trying to blend in with the rocks or is there something else going on?
I have not seen any aggression yet so I don't think they are starting to pair up and chase off any of the competition although I am expecting that any time now.
