Q: Can fish get sunburned?
Dustin – Jacksonville, FL
At some point in everyone’s childhood, a kindhearted teacher, seeking to encourage unrestrained curiosity, makes this simple pronouncement: “there’s no such thing as a silly question.” As adults, we know that silly questions do, in fact, exist. As a result, we tend to stop asking questions like “can fish get sunburned?” It’s just too silly to even consider. Sunburned fish? Ha! Hilarious! Except for one small detail: fish can get sunburned. The moral of the story? Your teacher was right. Keep on asking – and we’ll keep right on answering.
As it turns out, Koi fish in backyard ponds and water gardens are particularly susceptible to sunburn. Combine a shallow body of water, limited shade, and long hours of hot, summer sun, and Koi fish suffer from the aquatic equivalent of sunburn.
Like all other fish, Koi fish rely on a natural protective layer – otherwise known as a “slime coat” – that fends off everything from disease to injury. When Koi fish are exposed to too much direct sunlight, their slime coats are compromised, and sickness and lethargy follow quickly. Left unresolved, long-term exposure to sunlight will actually cause a Koi’s untimely demise. Fortunately, it’s a simple problem to fix – and we have the right supplies to do it.
To prevent aquatic “sunburn,” we strongly recommend the use of our Koi Shelter, which allows fish to take refuge from the sun before it causes damage. Like the Koi Shelter, our Aquatic Plants also provide excellent natural protection – along with the added benefit of aesthetic beauty. In addition to those solutions, creative pondkeepers also use rocks to create protective underwater caves, where fish can take a break from the sun’s rays.
Once you’ve taken care to provide adequate shelter for your Koi, the next critical step is to help your fish to restore its slime coat. For a simple solution, we recommend adding an appropriate quantity of salt to the pond. In cases where fish seem particularly lethargic, we strongly encourage the use of Fish Stress Reducer Plus to resolve the problem quickly – and bring your Koi back to health in short order.
Keep up the questions. We take them all very seriously.
