To keep the parrotfish's body color bright and vivid, the following points need to be noted:
Water Quality Management: Parrotfish are very sensitive to water quality, and changing the water regularly is the key to maintaining their body color. It is recommended to change the water every 2 to 3 days, replacing 1/3 to 1/4 of the total water volume each time. Keeping the water fresh can prevent the parrotfish from fading.
Water Temperature Control: The body color of parrotfish is the brightest when the water temperature is around 28 degrees Celsius. If the water temperature is too high or too low, it will affect their body color and even lead to health problems. Therefore, it's very important to use a heating device to keep the water temperature between 28 degrees and 32 degrees Celsius.
Lighting: Parrotfish are sensitive to light and need regular and appropriate intense light exposure. Keep them under intense light for 1 to 2 hours every day, and then let them rest in a darker environment. Avoid exposing them to light for too long to prevent stress on the fish.
Feed Selection: Choose color-enhancing feeds that contain astaxanthin or canthaxanthin, such as shrimp meat, dried shrimps, mealworms, and superworms. These can help parrotfish maintain their bright body color. Besides, vegetables like carrots can also be used as supplementary feeds.
Feeding Density and Environment: Keep a moderate feeding density and avoid mixing them with other large fish species to reduce the psychological stress of the parrotfish. The background color of the fish tank can be chosen as dark blue, and there's no need for special red lights for color enhancement.
By taking the above measures, it can effectively help parrotfish maintain their bright body color and good health condition.
