Have you got a goldfish with big eyes? Have you suddenly noticed your fish’s eyes look bigger than normal? You may be seeing a condition called “Pop Eye”.
Pop eye, also sometimes known as “exophthalmia” isn’t strictly a disease in and of itself, but rather, it is the result of another underlying issue or infection. It causes one or both of the eyes of the goldfish to protrude from the socket to some degree, ranging from a slight bulge to quite pronounced, depending on the severity of the condition.
The eye may also appear cloudy, but this is not always the case. If you notice your goldfish has big eyes, you should address the issue sooner rather than later, as it can lead to blindness.
Don’t forget though – some types of fancy goldfish are supposed to have big eyes. Goldfish like the Black Moor have telescope-style eyes, which is perfectly normal and not a sign that something is wrong.
