Is tank lighting bad for fish?

Answer 1

Properly lighting your aquarium is of vital importance and serves several purposes. We might think of fish tank lighting as simply a way for us to bring out the beautiful colouration of our fishes and make it easier for us to enjoy them. Lighting is however very important for the tank inhabitants as well. Many fish species are affected by light, and will for instance appreciate if you arrange dusk and dawn periods for them since this might be when they are as most active in the wild. Plants are even more dependant on light than the fish, since plants need the light in order to perform photosynthesis. Without proper fish tank lighting, they will starve which can cause them to stop growing or even kill them. If you keep invertebrates like corals, sufficient lighting becomes even more important since corals require huge amounts of intense lighting to survive.

Incandescent bulbs are the mildest form of fish tank lighting, and should not be used as the only light source for more demanding aquariums. Today, incandescent bulbs are often used as extra lights in aquariums that need some additional decorative lighting.

When fluorescent light was introduced to the hobby, it made it possible to keep much more demanding plant species than before, since fluorescent light is much more powerful than incandescent. Even if you keep sturdy plants that survive without fluorescent lights in the aquarium, you will usually notice a rapid increase of the growth rate if you provide them with fluorescent lights.

Metal halide lamps are stronger than fluorescent lights, and are necessary if you want to keep extremely light-demanding species such as certain types of corals. Metal halide lamps are therefore commonly found in marine reef aquariums. Metal halide lamps are also used as fish tank lighting for very deep aquariums, since weaker lights can be incapable of penetrating the water all the way down to the bottom of a deep aquarium.

Well it depends on how long you actually turn on the light. It doesn't matter how powerful or how different the brands of lights you may purchase, but it matters on what effect it will have on your fish. at night do not leave the light on as this disturbs the fish's sleeping pattern. If you choose to get a light, try to limit the hours of it on. The bad effects is that fish will not get enough sleep, light will encourage green algea growth, which can over grow on your tank, killing plants and fish in its way, and it is just bad for your electricity bill. As long as you have a window, lights are not really nessesary. In the morning light might come through the window and throughout the day, of course light will be there.

that's actual` too many fish. i does not positioned that throughout my fifty 5 Gallon not to show interior the 20 I certainly have. the ghost catfish would be lots too super for the 20 gallon. 2-3 angelfish want extra room then that. this is 20 Gallons for the 1st Angel and then 10 Gallons each for the subsequent 2. as a result you like a 40 Gallon tank in simple terms for the Angelfish. they are additionally in fact a tender fish; your water parameters would desire to be stable and appropriate for them.

Answer 4

No. Ideally, your fish tank should be on a timer with a twelve hour on off cycle for the lighting. Alot of aquarium fish are easily stressed and one of the things that will stress them is inconsistent light cycles.

if you have a saltwater tank you need the lights or everything will die. if you dont have live plants in your freshwater you really dont need a light if they r in a lighted room(if your tank isnt too large) if you have live plants you need lights to be on for 10-12 hours a day. the larger the tank, the more powerful lighting you need
