Neutral water contains an equal balance of hydrogen ions and hydroxide ions. If small quantities of water are needed, reduction of pH is generally a simple matter and can be achieved through peat filtration. When using a strong acid to reduce the pH, be sure to run several tests to determine how much acid is required to reduce the pH of a given amount of water to the desired level. When handling strong acids, review and observe all safety precautions to prevent accidental spills or exposure to eyes and skin. Many species of fish produce eggs only once a year while some others produce eggs repeatedly over the course of a spawning season.
Lemon tetras fall into the latter category.
During each ovulation, a female will spawn an average of 23 times producing an average total of 160 eggs. Ovulated eggs are sinking and slightly adhesive with diameters of 0.74 mm that swell to 0.90 mm after water hardening. Fertile eggs hatch in about 24 hours and there is no parental care given to the eggs or fry. This may lead many aquaculturists to believe that there may be an unlimited ability for males to fertilize eggs. However, Nakatsuru and Kramer found that there may indeed be a limitation to the males ability to fertilize eggs.
