However, for maintenance purposes the pH of the aquarium water can range from 5.6 to 7.4. However, if captive reproduction is to be attempted, the rummy-nose tetra needs soft, acidic water. A planted aquarium is welcomed by these fishes, particularly if the plants include fine-leaved species such as Cabomba and Myriophyllum.
The toxicity of ammonia is dependent on both pH and temperature and an added complexity is the buffering effect of the blood/water interface across the gill membrane which masks any additional toxicity over about pH 8.0. The management of river chemistry to avoid ecological damage is particularly difficult in the case of ammonia as a wide range ...
A shoal of neon tetras in a home aquarium. In the wild they inhabit very soft, acidic waters (pH 4.0 to 4.8) [16] Ideal pH for aquarium is 7.0, but a range of 6.0 to 8.0 is tolerable. [17] They can have a lifespan of as long as ten years, [18] but normally just two to three years in an aquarium. [19]
The pond loaches prefer a water pH of 6.5–8.0, but, as a temperate-climate freshwater species, will tolerate far more acidic conditions, even for extended amounts of time, with little negative reactions. This makes the pond loach a great choice for first-time aquariums and for those who want a hardy fish tank able to withstand a few mistakes.
If flake foods are used, care should be taken to prevent all food from being eaten by faster moving fish at the higher levels of the tank. [ citation needed ] Most Corydoras prefer water with a slightly basic pH between 7 and 8 [ citation needed ] , and temperatures between 72–78 °F (22–26 °C) They do not do well in fish tanks with high ...
In an experimental aquarium facility, clownfish were sustained in non-manipulated seawater with pH 8.15 ± 0.07, which is similar to our current ocean's pH. [115] To test for effects of different pH levels, the seawater was modified to two other pH levels, which corresponded with climate change models that predict future atmospheric CO 2 levels ...
