Fish have special adaptations that leave us breathless in their complexity.  Read about tuna and their amazing fins...

For months fish that live in dark caves in Mexico go without food. They have gone far longer—millennia—without light, evolving to lose their eyes and skin pigments.

Now researchers have discovered these strange creatures have another oddity. To survive their food-scarce environment, the fish have evolved extreme ways of turning nutrients into energy.

In the past few years, research has shown that fish feel pain.  The question of whether or not fish suffer was the subject of a recent conference...

We are constantly reminded not to feed our Koi too much - both for the sake of Water Quality, and for the health of the Koi.  And this time of year, some of us are not feeding at all because the water temperature is blow 50 degrees.  But is it possible to feed the Koi too little?

While this research pertains to wild fish, one of the species studied was Crucian carp, and it shows how easily are fish are affected by environmental agents that are not under our control.

The text below is the recommendation of Fish Veterinarian Richmond Loh of Australia, and is suitable for all fish - both Koi and aquarium species.  Please read the notes after the article...
