Bloated/Pregnant Glofish

[Shaely]

I'm fairly new to aquariums, but it seems one of our Glofish has something going on with it...It's either pregnant or severely bloated. I'm wondering what I can do to help or if anyone knows what might be going on? Thank you!

Hi and welcome to the forum

How quickly did it get fat?
If it got fat overnight or over a couple of days then it's a problem. If it gained weight over several months it's more likely to be eggs.

Is the fish still eating?
If the fish is no longer eating then it has an internal infection and should be euthanised.
If it still eats normally and is swimming around normally, then it's less likely to be an internal infection.
