My friend has two goldfish in a 5 gallon tank. They're full grown and 4 inches long. One of them has pop-eye, what can I recommend to her?
Hahaha. Yeah I tried to tell her this but she said "They're fine!" and got really defensive. I know they get huge. I told her to put them in a 75 gallon tank. She's gonna throw them in my pond and they're probably going to die because I'm sure they're stunted and diseased.
