Leave the light on during daylight hours, and turn it off at nightime.
it doesn't it gives the fish nutrients that only the light can give it should only be on 6 hours the max
You should be aiming for between 8 and 12 hours. about the same time as the sun is up. this helps with the natural environment of the tank, the plants will grow nicely, there wont be loads of algae everywhere, and your fish will behave more naturally. this can obviously be adjusted to suit when you will be looking at the tank, after all your paying for it :P. I have mine on around 11am-9pm because this is when im most likely to be home! too light can lead to an algae bloom and make your tank go green, if this happens don't leave your tank on for so long. it might also help to keep natural sun light off of the tank. tom :)
Fish should be left to defrost in the fridge for approximately 24 hours before cooking to ensure it thaws safely and evenly.
6 hours
Cooked fish should not be left out at room temperature for more than 2 hours to prevent the growth of harmful bacteria. After 2 hours, it is no longer safe to eat.
Yes, they do. But, too much light is not good for black moor fish or any other fish. Keep the light on for 8-10 hours a day.
24 hours
up to four and a half hours
Yes, it is recommended to keep a light on in a fish tank for about 8-12 hours a day to simulate a natural day-night cycle for the fish and plants inside.
No fish likes direct light. They hunt for other fish, so your lure should either sparkle or jiggle(to look like a wounded fish). Live bait should be very lively where possible
No. In pet stores the fish do not have lights on 24/7 as you said anyway, Fish do not have eyelids so they cannot shut their eyes to sleep, this means they need pure light to see and pure darkness to sleep. I keep the light on for something like 6-9 hours per day and leave the light of at night so my little fishee wishee's can get some sleep. Its good for the tank to look pretty as with the lights but just think; if you had to try and sleep with lights beaming down on you?? Hope this helps ........................................................................................................................................... also if you have an aggressive fish (like i do) ex Florida gar fish, piranha or Oscar leaving the light on 24/7 can irritate them and actually make them more aggressive
Keep it on for 6 hours then shut it off so your fish get light but wont fade also to keep you light from burnig out
