If you bought a fish from a store that has lights on 24-7 should you put a light on the fish at night?

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

Why do you think stomata shut at night?

To stop water loss from the plant. In the day light photosynthesis is taking place and carbon dioxide needs to be admitted into the stomata for this process. At night, no light, so plants, who lose water all day long, as it is replaced by the roots, shut the no longer needed stomata to conserve water.

Do the fish bite at night on lake of the woods?

It depends on what species of fish you are looking for. Walleyes typically do not bite at night. Burbot (eel pout) do. Northern pike do not. The walleye bite is not typical of all lakes, but is specific to Lake of the Woods, that they shut down at sunset. Ice-out is an exception.

What does eyes the shady night has shut mean?

The phrase "eyes the shady night has shut" suggests a sense of rest or sleep, indicating that the night has enveloped the world in darkness, closing off the light and activity associated with the day. It evokes imagery of tranquility and perhaps a protective silence, as the night offers a respite from the chaos of daily life. This line can also imply a metaphorical closing of the eyes to reality, inviting reflection or introspection during the night.

Can fishes see anything when they sleep?

It is hard to say for sure, but fish enter a state of rest - but do not completey switch off the way humans do. The fish needs to be on alert constantly to avoid being eaten by predators. At night if I wave my hand in front of the tank (with a dim light in the room) the resting fish scatter, so one would assume they can "see". It is also important to note fish dont have eyelids, so they can't "close" their eyes and shut out the picture. Similar to snakes.
