What else can I help you with?
Why does fish seem to be nearer the surface of the water?
It's caused by light 'refracting' as it travels from liquid to air. This makes the fish appear in a different place to where it actually is. Try it yourself - take a tumbler of water, and slowly slide the end of a pencil into the water at a slight angle. You'll see the pencil 'bend' where the water meets the air !
Why do objects underwater seem to be bigger and nearer than in reality?
because of refraction
Which instrument could be used to make distant objects seem larger and nearer?
Telescope
Do you have to take out the fish when changing the water?
It depends on if you are doing a complete water change or a partial water change. I usually just leave the fish in and siphon off about half of the water than replace the water. The fish get a bit nervous but seem to be fine with being left in the tank. To answer your question: No, you do not have to remove the fish when changing the water.
Why are fish not where they seem to be in a fish tank?
Light hits the glass and water at one angle and leaves at another angle (refraction). So, the light that causes you to see the fish has been interrupted in this way. This is also why fish (and other objects) are not where they seem when you look at them from above and not through glass.
If you sit nearer the middle of a seesaw will you seem to be heavier or lighter?
You will seem lighter because you're reducing the lever arm between you and the fulcrum (pivot point), thus requiring less force to balance the seesaw.
What scent do fresh water fish enjoy most?
All fish seem to LOVE garlic. You can get garlic food soaks or fish food infused with garlic and the fish go crazy! I attached some links...
Why does a fish die very quickly when it is out of water?
Well, the fish needs water to survive because its gills need to be wet to work, so it dries out when not in water and it can't breathe. Having said that, some fish seem to be able to survive postal journeys wrapped in damp moss!
Why do children like looking at pictures?
Because pictures seem attractive to them and more nearer sketch of life than words
Where do you have to aim to hit the fish for spear fishing?
What to remember when spear fishing:When light passes through air, it travels in a straight line. However, when light passes from the air to the water, or water to the air, it is bent, or refracted. When light passes through any two substances of different densities, the light changes speed and is bent.We think we see exactly where the fish is. Actually, the fish is lower than we perceive. It appears closer to the surface than it actually is. If you put the tip of your spear in the water, it will seem bent.The secret of spearing fish is to know how much below the image to aim the spear. The fish isn't where you think it is!The greater the angle (from the vertical) the fish is viewed from, the more the light is bent. Spearing from directly above, the fish will appear to be in the same place, but will appear bigger and closer to the surface than it really is.
Does water reproduce?
Some do. Certainly aquatic ones such as whales and dolphins.
How far open should you have the valve on your bubbler in your fishtank?
The valve on your bubbler in a fish tank should be adjusted to create gentle surface agitation without causing excessive turbulence in the water. A good starting point is to open the valve halfway and then fine-tune it based on the needs of your fish and plants. Observe the behavior of your fish; if they seem stressed or are struggling to swim, reduce the airflow. Conversely, if there is insufficient surface movement for gas exchange, gradually increase the airflow until you find a suitable balance.
