Ive got a Nikon D3100. Ive never used it for taking pictures of fish i bought it for taking pictures of cars that i have to say is alot easier then fish
And there Cardinals. They have a long red stripe under them but the picture isnt great for showing that.
Definitely cardinals. Sometimes the red can be a bit washed out, and often it's the camera that does that. Nice shots, they're difficult to keep in frame.
