As you may (unlikely) or may not (likely) have known, both of my female danios have been bloated for quite a while. Actually, they've been this fat ever since I got them. I'm pretty sure it's not a disease, I've had them for more than a year, and they're all perfectly fine. At first, I thought that they were pregnant, but I never found any eggs or fry (unless they ate them), and my females never god a bit slimmer. Never ever. Or is this normal? Anyone have any ideas?
