The acidity for tropical fish? I think your referring to the acidity of the water in their aquarium...???
Generally, "tropical fish" do well with a neutral (7.0) or slightly acidic (6.7-6.9) PH level in the water of the tank. This is easy to test using a PH test kit from your pet store.
The acidity of the water is affected by whatever is IN the water with the fish---in the wild, the flora and fauna of the area dictates the PH (acid-neutral-alkaline) of the water. In general most of the common tropical fish (freshwater) sold in pet stores come originally from central/south America and Asia. The waters in these areas are slightly to mid level acidic depending on the time of year. These fish would be the common "community" tropical fish like tetras, gourami's, live bearers (guppies, mollies etc) and algae eaters/scavengers. The larger "cichlids" like Oscars, Jack Dempsy's etc are also from South America but are aggressive.
All do fine with an PH (acidity of 6.8-7.0) as most are commercially raised now anyway.
Don't put "wild" rocks in your tank as they could contain pollutants and be very calcium rich (like sea shells) and raise the PH to above 7.0 into the Alkaline level.
Some fish (like the African Cichlids) prefer a high alkaline environment...
Hope this helped,

∙ 13y agoThe pH of a saltwater aquarium should be kept between 8.1-8.4 for the most part.
There are a few corals, mainly some sps corals, that live much better in the slightly lower pH range of 8.1-8.2 due to their finicky slight finicky nature in the home aquarium it is best to keep your aquarium at this level which is still perfectly find for all other corals and fish.
There are a few rare fish such as a peppermint angel, and the narcosis angel that are collected at much deeper waters, the pH needs to be slightly lower for them to thrive but they can live in a reef tank that has a slightly higher pH range.

How does acidity effect tropical fish?
The acidity of your tank water can kill your fish or make them sick. Before deciding on what fish you want to put in your tank; you should ask your local pet-store what kind of water the fish prefere. Some fish like hard water (high acid) and some fish like really soft water (low acid). Most fish at the pet store will be happy in moderately acidic to soft water. I keep my tank at 7.0 on the pH scale.
