They prefer water with a 6.0 - 8.0 pHAlternate uses: see Ph pH (potential (of) hydrogen) is a measure of the concentration of hydrogen ions (H+) in a solution and, therefore, its acidity or alkalinity. The concept was introduced by S. Sorensen in 1909. The p stands for the German potenz mean, a water hardness of 5.0 - 19.0 dGH, and a temperature range of 73-82 F (23-28 C). A nocturnal fish, they use an electric organ and receptors distributed over the length of their body in order to find insect larvae.
