* below 12C / 55F you should stop feeding your fish. Above these temperatures, you should slowly start feeding again.
Temperature control is essential for the health of your fish. The increase in temperature can increase free ammonia levels, decreasing oxygen and lead to high levels of bacteria that could cause illness.
