Hi just thought I'd ask the question has anyone had a clownfish that changed colour and is it normal? I bought a clownfish about a year ago it was normal orange and white with black outlines however in the past few months it has partly turned black is this a sign of maturity as it is the bigger of my pair and the smaller clown hasint changed. It is an Ocellarus or Percula I can't tell the difference myself, can't get them to stay still to count fin spines.
