That is part of nature's camouflage to protect the fish. The fish coloration, as you descibe it, makes it more difficult for a predator (fish or man) to see the fish from above (dark against the dark background of the water and sea or lake bottom) and from beneath (light against the light background of the sunlit atmosphere). This camouflage scheme has evolved over the centuries; those fish that were not so protected did not survive as well as those that were, and did not produce new generations as efficiently.
What else can I help you with?
Why do frogs have a light colored bottom and a dark top?
Think of it like this..... If a predator is looking down from the sky, the dark top of the frog will blend well with the ground and dark waters. And if a predator under the water looks up to the surface, the bottom of the frog would blend well with the sky. So frogs have light bottoms and dark tops so they can blend well in their surroundings and be safe from most predators! :)
Can fish see in the dark?
Most fish have good night vision, but they can't see in complete darkness. They have adapted to low light conditions and use specialized cells called rods to help them see in dim light. Some fish, like catfish and carp, have particularly good night vision due to a higher number of rods in their eyes.
How the fishes get food?
Most fish can be fed fish food. If not they feed on algi, a bacteria that grows on the seabed and plants or the glass walls and bottom of a fish tank.
When should the light over the fish tank be on?
You should be aiming for between 8 and 12 hours. about the same time as the sun is up. this helps with the natural environment of the tank, the plants will grow nicely, there wont be loads of algae everywhere, and your fish will behave more naturally. this can obviously be adjusted to suit when you will be looking at the tank, after all your paying for it :P. I have mine on around 11am-9pm because this is when im most likely to be home! too light can lead to an algae bloom and make your tank go green, if this happens don't leave your tank on for so long. it might also help to keep natural sun light off of the tank. tom :)
What does it mean when a betta fish lays down at the bottom of the fish bowl on its side?
A betta fish laying on its side at the bottom of the fishbowl could indicate illness or stress. It may be suffering from a swim bladder issue, which affects its buoyancy. Immediate attention from a vet or a specialist in fish care is recommended to diagnose and treat the problem.
Are there animals that do not require sun light to live?
yes. offhand, most of the fish at the bottom of the ocean do not require sunlight.
Can fintail goldfish see in the dark?
I think you mean "Fantail" and the answer is goldfish can see no better or worse in the dark than most other fish. They are normal in their light requirements.
What color is a fish before dying?
Most fish get very light colored when stressed, but some become very dark. Basically, a drastic color change indicates a problem.
Do bottom fish have brighter colors compared to surface fish?
No. In actual fact, since there is insufficient light for colour to be seen in the very deep ocean trenches, most deep water fish are lacking in colours.
When fish spend most of the day on top of the fish bowl what is happening?
depends what type of fish it is most of the time when a fish is on the bottom it means its sick or depressed but your fish is probably healthy

What the camouflage mechanism that causes frogs to be dark on the dorsal surface and light on the ventral surface?
This is one of nature's most common camouflage methods for creatures that live in, or spend a lot of time in, the water. When viewed from below, they blend into the (lighter) sky. When viewed from above, they blend into the (darker) bottom of the pond or lake. Most fish also have this color arrangement.
What color most absosrb light Dark or light?
Dark colors absorb more light than light colors because they contain higher levels of pigmentation, which allows them to absorb and retain more light energy. Light colors reflect more light and appear brighter as they do not absorb as much light.
When light hits a dark object then light is absorbed?
Yes, dark objects absorb more light than they reflect. This is because dark objects have pigments or materials that absorb most of the light that strikes them, which is why they appear dark to our eyes. The absorbed light is converted into heat energy.
Does light blue go with dark pink?
Yes most likely but it depends what your light blue and dark pink look like.
What does not give off its own light?
People, trees, flagpoles, most animals (although the Japanese have bred "glow in the dark" fish and cats) , planets, moons, and other items that only REFLECT light.
Does my fish need light to survive or become healthier?
Most fish prefer to live in a well-lit tank. Lighting enhances the colours, and also allows live plants to grow, and fish prefer living in an environment with live plants. Fish constantly kept in the dark will probably be stressed and their eyesight may be affected.
