My tetra looks ready to burst. By which I mean, it has suddenly gotten really fat. I have it quarantined for now. What I'm wondering is, sick or pregos?
Its hard to tell from the photo but it is not pine coned, it seems to swim normally and will still eat. I actually went a few days without feeding it but that didn't help. So I tried feeding it very small amount of peas, but that didn't help either. Am I missing anything?
Thank you in advance for all your help!
