Do your fish have patchy discolouration?

[LukeSivyer45]

Hello everyone, I’m curious to know if your fish and maybe wrasse in particular as I have had 2 wrasses which from most angles look fine such as my photo but sometimes when the light hits them at a certain angle or in natural light there are discolouration patches? My first thought is flukes but considering he shows absolutely no other symptoms it doesn’t make too much sense to me. I read on other forums that some peoples wrasses just bump rocks and lose scales causing the discolouration but as I said I am curious to know if anyone else has had a similar experience

Are there scales missing? If not, I'd bet it is just the light refracting off the scales and making them appear a different color.

Thats an interesting point! Yea I had that thought initially and keep thinking it. Do you think the refracting of scales can occur in natural light as well as under the reef tank light?
