Histology of Fish Body

Now Dig In, I will share some Things that will know what is actually going to happen inside the fish body. This Fact will tell you why fish change its colors slowly and Rapidly?

Firstly, Slow colors Changes Happen, when it comes to the Birthing Growth from Larva into individual. This is the slow process of converting a specimen into complete body. In Initial stages, they have no prominent colors. They have fade ones. When the time is passing With the Age they are changing its original colors, which are genetically inherited from parents.

Secondly, Rapid color changes are due to Stress or Aggression. Some Fisher Man also see when a fish caught into a hook. They show rapid color change in it.

Finally another Reason behind the colors change is these two types of cells that are present on the upper layer of a fish skin. First one are “Chromatophores” and secondly “Iridocytes”

Fish Food

By common Sence, Fish Feed has no effects on your fish colors but it has drastic effects on your fish health. But Feeding Low Quality for a long time can have GREAT effects on your fish colors. Food is not directly concerned with fish coloring but Continuous dose of crappy food leads to Bad health. When your fish will fall ill. It will start loosing its good colors. She will look Dull or dumb. I am using Branded foods like TetraColor Tropical Flakes with Natural Color Enhancer.

Water Parameters

Water is Something that may lead to the death of your Sweet Pet. In case of any live bearing fish. Water plays an important role as food and oxygen for life. If they are not provided with quality water (WELL maintained Ph and temperature) the color of your fish maybe turn into Pale or light colors. The nature of water and PH must be alkaline. The percentage of Ammonia must be Zero. Nitrites and nitrates must be 20ppm. The water changes must be done on a weekly basis. The water temperature should be 28-degree Celcius. Use the Right Aquarium Heater for this Purpose.

Aquarium Lighting

It’s another factor that needs your eagle eye attention. Choose your Aquarium Lights very wisely. Let me tell you how it affects your fish colors. I have compiled a complete Guide on Best Aquarium Lighting for Fish Color. In most of cases, all Freshwater fish Shows Colors in just a small amount of light.More bright colors of light used To promote fish colors. They get shining or shimmering, when they are kept in Bright lights with 10,000k intensity. You will get More Blue Or Dark shades. On the warmer Colors, Fishes Lose its original colors or They may get fade or Dim. The Light That are used to loose fish colors having 6800k to 8000k of intensity. These lights Promotes Yellow, Red, Browns and Greens. So always make Wise Selection While Setting up lights on the fish tanks in right direction and placement.’

Diseases

It is not natural thing that a fish might change its colors or get dim or fade colors or may be have some dark ones. There is ultimate reason behind them. Carrying a disease is one of them. For example if your gold fish is changing its color and turning into black. That is suffering from fin rot that turns the fins into black. It is Most Common Thing In Goldfish and Koi.
