Salmon Over Stream
We are behind fences so getting the right angle for a reflection turns out to be hard. Salmon returning to the creek turned out to be a theme.
Glowing Goldfish With Rock
This image was a real coincidence of light. The glowing fish (caused by murky water) only really showed up where the fish was in sunlight but most of the image was in shadow.
Nara With Small Fish
I'm pretty sure this is a Brook Stickleback. They were common in the lake (the kids had no problem catching them). These could be full sized fish - they don't grow much larger than this.
Hawaiian Spotted Toby
The guide books says these little fish are aggressive to other fish, but can't do much to swimmers. The aggressive nature is why they are easy to see for snorkelers.
