If your fish are consistently surfacing, it means that they are gulping for air.
You should do an immediate 50% water change, and make sure that you add the recommended dosage of water conditioner to the tank when adding the new water back in.
Also, make sure that you test for ammonia, nitrites and nitrates which should be 0, 0, and less than 10 respectively.

Why the position of the fish inside the water seems to be at less depth than of its actual position?
Light coming from the fish under water deviate from its original path due to refraction phenomenon and its image is displaced from its actual position. The image of fish is appeared at shallower depth than its actual depth
Why position of fish inside water seems to be at less depth than that of its actual position?
When light travels from water to air, it changes speed and direction due to differences in optical density. This causes the light to refract, making objects appear higher or shallower than they really are when viewed from the surface. So, the fish might look shallower in the water due to this bending of light.
What is apparent depth?
If a person looks at a straight object, such as a pencil or straw, which is placed at a slant, partially in the water, the object appears to bend at the water's surface. This is due to the bending of light rays as they move from the water to the air. Once the rays reach the eye, the eye traces them back as straight lines (lines of sight). The lines of sight (shown as dashed lines) intersect at a higher position than where the actual rays originated. This causes the pencil to appear higher and the water to appear shallower than it really is. The depth that the water appears to be when viewed from above is known as the apparent depth.
Can you see someone in deep water due to refraction of light?
Yes, due to the bending of light underwater, objects can appear distorted or shifted in position. This can make it difficult to accurately determine the depth of the water or the exact location of objects below the surface.
Why does the coin appear to be nearer the surface of water?
When a coin is placed in water, light rays travel from water to air and get refracted. This refraction makes the coin appear to be nearer the surface of the water than it actually is. This is due to the change in speed of light as it moves from water to air, causing the coin to appear to be at a different position than its actual physical location.
What does the coin that lies submerged at the bottom part of water looks?
As the coin submerged in water and kept at the bottom of the vessel and if it is looked right from the top then it will appear to be lifted up by a small distance such that the actual depth / apparent depth = refractive index of water. If suppose the actual height of level of water is 12 cm then the coim will be shifted up by 3 cm. So the apparent depth will be 9 cm. Hence refractive index of water = 12/9 = 4/3 = 1.333.
Why the position of fish inside the water seem to be at less depth than that of its actual position?
Light coming from the fish under water deviate from its original path due to refraction phenomenon and its image is displaced from its actual position. The image of fish is appeared at shallower depth than its actual depth
Why does a straw appear bent when placed in water?
When light passes through water into air, it changes speed and direction due to the change in density. This change in speed and direction causes the light rays to refract, making the straw appear bent at the water's surface. However, the actual position of the part of the straw in the water remains unchanged.
Does refraction tend to make objects submerged in water seem shallower or deeper than they really are?
Refraction tends to make objects submerged in water appear shallower than they really are. This is because light rays bend as they pass from water to air, causing objects to appear higher than their actual position.
Why does a pond appear shallower than it really is?
Due to refraction. When light travels through a denser substance, it bends towards the normal, so things appear to be at a different angle, size or depth than they really are.
Which information is most important when passing near a lighthouse?
Depth of water
How much water is needed to fill an oval above ground pool that is 30' by 15'?
The calculation for an oval pool is: Length x Width x Water Depth x 5.9 = Total Gallons Please note that the water depth is the ACTUAL water depth, not the wall height (the water is typically 6" lower than the wall). For your example, let's assume an actual water depth of 3.5 ft: 30 x 15 x 3.5 x 5.9 = 9,293 gallons or about 9,300 gallons. Hope this helps ... http://www.poolspa.com/calculator/
