Your Goldfish is NOT Constipated
What is “constipation?” It is the inability to pass fecal material usually due to dehydration or lack of fiber in the diet. Thankfully, goldfish are physiologically built to never be constipated.
Why is my goldfish NOT constipated? Imagine a goldfish swimming in their tank. Remember, goldfish are freshwater fish. Now, the next part might require you to pull out your high school chemistry notes or ask your child to explain the following concepts. Goldfish live in a hypoosmotic environment, whereas they are more dense than their surrounding water. Through osmosis, water is constantly moving into a goldfish to create equilibrium, essentially super-saturating a fish’s tissues.
