For those of you who don’t know, the species my research focuses on, is the three spined stickleback. I took the picture in the header last year to test out how well my camera copes with taking pictures through aquarium glass. The answer is “not very well”. The fish is one of my males in breeding condition, but as usual in our facilities, he looks quite pale. Not sure what that’s about. Either way, that’s why he has lovely blue eyes.
