Never posted before but could do with some advice. I have a bristlnose cafish that, well..........seems to change colour! During the day he's a great light/dark mottled brown colour but at night with lights off, he goes a peculiar shade of pink mottle. My water parameters are fine and none of my other fish (Harlequins, guppys, shrimp and corys) bother him. He seems to be feeding ok and there's no outward strange behaviour from him. Just wandered if any one else had any ideas.
Cheers.
