A study conducted in Manaus, Brazil, subjected cardinal tetras to adverse water conditions for 96 hours. The fish perished at a low temperature of 19.6 °C (67.3 °F) and a high of 33.7 °C (92.7 °F), and pH below 2.9 or above 8.8. [5]
Yellow perch have been proven to grow the best in lakes where they are piscivorous due to the lack of predators. Perch do not perform well in cold, deep, oligotrophic lakes. Seasonal movements tend to follow the 20 °C isotherm and water temperature is the most important factor influencing fish distribution.
For a tropical fish tank, maintaining a warm environmental temperature ranging between 75 and 86 °F (24 to 30 °C) enables different tropical fish to thrive at different temperatures. [2] Aquarium substrate usually consists of sand or gravel. Aquarium substrate is important for the fish's health and replicating their natural environment.

[58] can live in full sea water [59] 66 °F - 84 °F (19 °C - 29 °C)
This makes it an ideal fish for keeping in an unheated aquarium in cold climates. In fact, White Clouds are more active and healthier when kept at temperatures lower than those at which most tropical tanks are kept. Water hardness should be from 5 to 19, and pH levels should range between 6.0 and 8.0. Also, the aquarium should have a top.
