Just wondering, is it okay to leave your aquarium light on 24/7? Does it affect the fish in any way?

Answer 1

Hy there! My real name is Danilov and I'm a vet specialized on exotic and tropical fish. I have over 150 species in my private aquarium(s). I think I can help you with your question.
The recommended daylight for an aquarium is about 16h/day. As the person that has answered above me, it depends if you have aquatic plants. But let's not forget the main reason for that you have asked the question: does this much light effect your fish. The answer is yes. When I started this fish mania of mine I was 13 years old. My dad bought me a 12 liters aquarium (tank) and a basic filtering apparatus, on air, you know thw ones with a sponge. I didn't have money for a neon for the fish so I kept them only on sunlight. The fish grew very well, I mean I hadn't any problems regarding the lighting. When I placed them on artificial light , their food eating pattern changed, and son they started to die. My advice. don't keep them 24/7 on neon light. during the day turn off the light(s). You will find this also economical, your electricity bill will go down substantially.

Answer 2

Yes it is okay. This will not cause any significant changes to the aquarium's water chemistry. Nor will it affect the health or growth rate of the fish. BUT there is one condition that can occur from 24/7 lighting.

Constant light over a long period (12 months or more) can lead to a complete depletion of one specific vitamin (sorry, can't remember which one) which causes the fish to go blind. No joke. I lost a prized fish (Harlequin Tusk) to this condition because I didn't know about it.

This happens very,very rarely and may only effect one fish in a tank of thirty. Turning the lights off at night say once a week will make sure it never occurs.

Cheers

Fish like humans do need time to rest. Fish are not nocternal animals, thus they typically rest when it is dark. 24/7 lighting will stress the fish most likely causing them to get some kind of infection.

The adverse effects on your aquarium would be alot. Algae growth, fish stress, water chemistry (if you have live plants), and others. I don't recommend 24/7 lighting. Get a timer at your local hardware store if you are forgetful.

Answer 4

it will affect your fish. Apart from the fact that algae will probably run rampant in your tank, fish need sleep. Now they dont have eyelids so they cant close their eyes. It very hard for us to sleep in the light, imagine if we couldnt close our eyes!

16 hours a day is stupid, if you go and look at the tropics, they have 12 hours a day. This is the reccomended amount of light for planted aquariums, and that is with low lighting at first with a strong miday peak. 8 hours is the absolute max for non planted tanks, though your fish only need a few hours of light. The light is mainly to let us see the fish

Answer 5

It is fine to leave it on.
The only adverse affect it will have is it will speed up the growth of algae on the sides of the tank.
It uses energy too, so you could always leave it off during the day and on at night.
I've never heard of any horrible problems in fish from having too much light.

The clear out needs to run in any respect circumstances, it is what keeps their little ecosystem. you attempt to imitate their organic surroundings, and it truly is a comfortable stability. the mild ought to only be used round 10 hours. imagine of it as preserving their organic habitat. The solar is only out area of the time. we do not turn our lighting fixtures fixtures on till late afternoon particular circumstances of the 365 days, the solar is sufficient in our living house. (no direct photo voltaic, in spite of the indisputable fact that.) Their nighttime cycle should be an similar as yours, it is the perfect way. too a lot mild motives extra algae boom. for that reason, keep your tank faraway from direct photo voltaic, and do not position it instantly close to a window. in case your tank is already close to a window, keep the blinds or curtains closed, so the organic mild will nevertheless clear out in, yet no direct photo voltaic will. The direct photo voltaic will also warmth your tank somewhat better, and considering they're goldfish, that is undesirable. For care, make positive you're preserving weekly water variations and gravel vacuums. Goldfish are the "dirtiest" of fish, meaning they launch distinctive ammonia with their everyday waste, so the weekly upkeep is a ought to. try their water in many circumstances, besides. you should purchase the try kits at your community fish keep. I keep a fish mag. I record tank temperatures, water parameters, clear out variations, any variations I be conscious contained in the tank, and so on. it is totally useful, i quite propose doing that. sounds like lots, yet like some thing else, once you get into the habit, you do not quite imagine about it. good success, have interesting, this is a astounding and rewarding activity. desire i have helped!

Answer 7

is it a tropical tank? tropical fish like about 14 to 16 hours of light, then a slow reduction in the light until completely dark.a gradual increase from dark to light is also appreciated.sub tropical species prefer about 12 to 13 hours of light with the same gradual increase and decrease.without these requierment met, your fish may become stressed.

Answer 8

The fish might be a little spastic, and you'll have a lot of algae, which'll eventually bother them. 8 hours a day is the max for most tanks, and that's for a fluorescent light.

Answer 9

If you have plants it will affect your fish as they put out oxygen or carbon dioxide depending on if it's light or dark. This will affect your PH levels.

Answer 10

It's OK but you Will get a over growth of algae make sure you have a algae eater of a pleco
