Hello, I've got 35-ish Glofish and Gold Zebra Danios in my 75 gallon tank. Some of them have been getting big bellies and I want to know if they're full of eggs or just a little Chunky. I know they don't get traditionally pregnant, but that's an easy way to describe it. I don't really want them to breed (hence no mop and the Dojo Loaches living with them), so if they're not pregnant, that's fine. I don't have a heater in the tank, but the temp floats around the mid 60s. The one in the picture is a pretty small Danio, but it's belly is probably the best example of what I mean. Sorry it's blurry, they're darty little things. Thank you for the help!
