When setting up an aquarium we must allways try and simulate the fish's natural environment as best as possible. If a fish is found in water with a PH range of 6.0 - 7.0 that will be the range we would try and keep with-in an aquarium. As for the question "Why should the pH for tropical fish be 7" that is a bit of a trick question as different tropical fish have different PH ranges.

If a fish tank needs a pH of 5, but at present it is at 7, more H atoms should be added to the concentration.
The same for every fish that is a freshwater fish: 7.
It shouldn't. A pH of 5.5 is much too acid to keep tropical fish. The only fish that will survive at this pH are species that are specifically adapted to very acid water, such as chocolate gouramis and some tetras. If you want to keep tropical fish, you will need to buffer the pH by adding something like oxy blocks to your water.

pH below 7 is termed acidic. pH of 7 is termed neutral (water). pH above 7 is termed basic or an alkaline.
Should be neutral pH = 7
To lower the pH of your tank from 7 to 5, you need to increase the hydrogen ion (H⁺) concentration in the water. This can be achieved by adding an acid, such as hydrochloric acid or a commercially available pH-lowering product designed for aquarium use. Monitor the pH closely during the adjustment process to avoid sudden changes that could stress or harm the fish.
7....But you should keep an good watch on them.
The pH level of water should be around 7, which is considered neutral. However, slight variations in pH are normal and acceptable for most applications.
Purified water should have a pH level of 7. The values of 7 is neutral on the pH scale.
no, it would be too acidic they probably could live in a pH range of 5-7 although it all depends on the type of fish
In an acid (pH <7) it should be the hydronium ion: H+ or H3O+ In a base (pH >7) it should be the hydroxide/hydroxil ion: OH-
