So, at what temperature can goldfish survive? Typically, goldfish can survive static temperatures between 0☌ and 41☌. One of the causes why goldfish are so widespread throughout the world, is their capability to tolerate lower temperatures.Īnd it is noteworthy that although many tropical fish have upper-temperature tolerance equal or even higher than goldfish, they don’t have enough ability to lower temperatures. In reality, goldfish can even tolerate temperatures equal to or less than 0☌. But the researchers also highlighted that it was difficult to achieve zero degrees celsius or lower temperatures in their CTMin trials. The mean CTMin in this study for goldfish was found to be 0.3☌. This result makes goldfish one of the highest upper temperature tolerating fish. In this study, the ultimate CTMax for Goldfish was found to be 43.6 ☌. The CTM endpoint is a temperature at which the fish starts making disorganized (locomotory) movements and loses the capability of leaving the conditions that can lead to death. This stage is termed as CTM endpoint (CTMax or CTMin). In this procedure, the fish are given a constant, continuous, and linear raise or reduction in temperature until a near-lethal but sub-lethal stage arrives. The Critical Thermal Methodology (CTM) has been used to measure the temperature tolerance of various fish species. And the critical thermal methodology was used in this process. Researchers studied the temperature tolerance of goldfish at constant acclimation temperatures of 5, 15, 25, and 35 degrees celsius. Then, they were placed in aquaria filled with dechlorinated Denton Tap water.Īll the fish were fed with Tetra-Min flake food every day. First, the goldfish were collected from Pet Stores in North Texas.
