sunlight is essential for fish? Can I keep fish without exposure to sunlight?
some examples?
Yes and no. Although many fish live their lives in the darkness of the deep ocean and in lakes in other fish do not need sunlight for themselves but for the food they depend for survival. Most of the fish during the hot summer sun is shaded to "hang out". While ambient light affects the color is not a requirement of most of fish. In an environment of deposition of artificial lighting is used, but more for the benefit of the observer is not the fish. While many require investing direct sunlight for various body functions do not fish. For example Rape born and live their entire lives under the surface of the ocean where no light. Just as the cave fish that over time have lost their eyes because there is no light to see, evolution has taken fish. While some argue fish such as salmon and trout need light to survive, there really is no proof. Even the salmon live in the deep ocean trout live in the depths of a lake where the water is great. Basically, the lighting in tanks or should I say the only fish tanks to simulate the cycle of day and night alone and really has no benefit for fish. Standard lighting does not work for photosynthetic animals in a tank. Ultimately it can keep fish in a tank without light
