One of my female otos have developed this:

I know this may just seem like a fat oto but this is another one of my otos in the same tank with a food baby not a real baby:

Hi Crepe, They could be carrying eggs, do you have any males? maybe you'll be lucky and get a spawning, can't be certain I know nothing about otto's, maybe you'll get some feedback from other members. keep us posted on what's happening, if anything.

I've got 2m/2f right now. But I think one of them might be of a different species. Anyways, it's been 2-3 days with no change. I think it's just one fat oto. lol
