I have a fresh water tank with 3 fish wanted to know if I can leave light on all the time or not?

Question

are you supposed to leave a fresh water fish tanks light on all the time or should you turn it off. or does it even really matter?

Answer 1

Leave the lights on for up to 8 hours a day so they can get the benefits fo the lights off and darkness. Also algae buildup will occur with too much light. Not a good thing for having a tank too have too much light all the time.

Answer 2

You should not leave the light on all the time. Fish do need to rest, how would you sleep if the lights were on 24 hours a day and you did not have eyelids? Also by leaving the light on all the time will raise the water temperature, possibly to deadly levels and algae will have better conditions to flourish. I recommend getting a timer, they cost less than $10 do not leave the lights on for more than 12 hours a day

First, for 2 goldfish, you will want a 30-40 gallon tank. for 3, you will want a 55+ gallon. 2d, the chlorine neutralizer and water conditioner the two eliminate chlorine. ultimate to get a water conditioner, handle the water, and nonetheless permit it take a seat for awhile. you are able to desire to cycle your tank. I constantly say, whether it somewhat is larger than your known 10 or 15 gallon tank, then it is cycled. in case you're making plans on a goldfish or 2 (a million=20 gallon, 2=30-40 gallon depending on species, do your study!), then you quite could virtually deffinately cycle the tank first. it's going to be some month long technique, regardless of the undeniable fact that it somewhat is definitely well worth it interior the tip. you will no longer would desire to purchase organic and organic micro organism in case you cycle your tank. cycling is a technique the place it of course builds up that micro organism. you basically purchase it, in case you at the instant are not likely to cycle your tank. Gravel, lights, and a filter out are a could. stay vegetation are not as significant, and definitely in all probability ultimate to bypass away out of a goldfish tank. Goldfish are little piggies, and could consume them. The Ph attempt kit is critical, as properly as kits to attempt nitrates, nitrites, ammonia, alkalinity, and hardness. yet another somewhat stable element you are able to have and did no longer checklist, is a gravel vacuum. it somewhat is a siphon hose used to eliminate water and clean the gravel for the duration of water differences (quite of pulling water from the astounding of the tank to alter, it takes it from the backside, alongside with poo and foodstuff that has been left between gravel). they're very obtainable to have, and could shop your tank cleanser. do only your study! With study, you're much less in all probability to fail!

You must turn it off during the night, couse they get estressed. Here goes an experience about a fish :
"My fish died last time I took a long time before getting more. I belive the problem was that I misjudged the size of the tank and over medicated them. I haven't put anything in the water except some liquid microbacteria, and just a bit of that. I didn't put anything in the water to declorinate it, I just let it sit for 5 days with the filter running. The water in Taiwan is very bad.
Now the problem. Yesterday when I got the fish they were all fine. I got two bottom feeders (yellow with black tiger-stripes) and some food for them. Today, I found one laying on the bottom of the tank and the other hiding under something. I turned off the light to see what would happen. The hider came out and started scutting around. The other perked up but didn't mover around much. When I turned the light on again, the hider hid again and the other flopped on his side. I've got the light off now, but the little fish (guppies?) are laying on the bottom when it's dark.
I've had trouble with fish and light before. I was keeping two newts in this tank with a small light just on one side. After a few days, the gravel and the decorations (little fence) had turned a burnt orange color. It cleaned off easily. I'm worried that there is something in the water that is reacting with the light. Or could it be the microbacteria that I added in?
Also, the one sick (non-hiding) bottom feeder's head looks black unlike the hider.
I don't know about the ph, nitrate, or ammonia values or how to go about measuring them....."

People recomend that you take all the fish out of the tank and set them in individual containers (temporaily) and tottaly clean out the tank...like a major clean out!!! then set your filter in then add all your objects and rocks in the tank. (make sure to soak all plants and rocks in a water conditioner for atleast an hour! then add water into the tank at about 72F and then put in some water conditioner into the tank (you can get it at local pet stores) mix it all around and then wait half an hour with pump on! then slowly add fish, smallest to biggest. (tropical fish love light so what i think is that you have to do is get another tank and put bottem hinding fish into another tank) .

This is a question with its answer that can help you about another way of caring them !
good luck !

Answer 5

algae is a problem when the light is left on all the time. also the fish need a natural environment which is day and night. but algae is the main problem with a light on alot. it makes it grow and can cause alot of work on your part. natural light is best. away from windows.

Answer 6

Wouldn't recommend it. That would be like having the sun out all of the time. It wouldn't hurt us, but it probably gets old for those few on the earth that have sun for 6 months at a time. Basically, you want to try to replicate their native habitats as best you can. Hope this helps! :-)

Answer 7

I leave mine on all the time, it helps to regulate the temperature without a heater. I don't have any problems with algae. I have 10 fish in a 10 gallon tank.

Answer 8

No, fish need their sleep too. I got mine on a timer, it goes on at 7:00am and off at 9:00pm seems to work well.

Answer 9

You can, but it is better to turn it off during the night to give the fish daylight hours and night hours like they would have naturally.

Answer 10

Yeah - Fish gotta sleep!
