There is only one fish in this picture - the one on the right. The other "fish" is a reflection off of the water at the top of the tank.
It was taken in a Dr.s office while waiting for an appointment as an opportunity. I appreciate the recommendations about iso, etc. so I can continue to learn. Thanks.
I don“t really find the image quality on this shot to be up to par with what will score well on DPC so try to use a lower iso setting and boosting contrast in post processing next time.
