can fish see color?
In a word, yes. According to Dr. Reinert, "One of the best indicators that some fish see color is
that they have cones, which are the color receptors in higher vertebrates. Another indicator is
that many fishes are highly colored, and the most colorful fishes are found in shallow,
well-lighted waters, where they are exposed to the full color spectrum."
Based on testing, the primary biological advantage of color vision for a fish is being able to
contrast food targets against a variety of backgrounds. As a fly fisher, you should know that
color can really impact a fly's effectiveness at times.
im gonna have to say yes they can see color fish actually have very good eye sight
the fish eye
Two major lens modifications affect the fish's vision profoundly-its lens is round, and it is
much denser than a human lens. A fish lens can, therefore, focus heavily-refracted light onto the
its retina, so it clearly sees objects underwater. To vary its focus, the fish moves its lens forward
and backward. A freshwater fish is naturally farsighted, so when it wants to focus on close
objects, it moves its lens back from the cornea and closeup focus is achieved. Fish enjoy a
tremendous field of view, with 180 degrees of overlapping vision from both eyes. With their
swimming motion and eye movements, fish generally don't have blind spots behind them and
have good depth perception.
haha. thanks for the comment! i had the "nature" look before and it wasnt working for me so i did a huge re make! thanks for the comment 
i wouldnt mind to see these guys get bigger, they are quite the fun fish to watch. especially feeding them they practically jump out of the tank everytime. Did you have a problem adding new fish with your danios? they always seem to attack new fish in the tank for a few days then leave them alone
