Male and female Glofish can be distinguished by their appearance: male Glofish are slimmer, whereas female Glofish have a more rounded, pot-bellied appearance. This natural appearance frequently causes female Glofish to appear pregnant when they are not.

Female Glofish, to be precise, are never pregnant. They are not live-bearing fish; rather, they transport and lay eggs. Animals are considered pregnant only if they are carrying live young. However, the term “pregnant” is frequently used colloquially to refer to a fish or animal that is carrying and ready to lay eggs.

When a pregnant Glofish is ready to lay eggs, she will appear slightly more rounded than usual. Because it can be difficult to tell if a Glofish is pregnant simply by looking at her, you should rely on behavioral cues instead.
