This is the only picture I could get, I've got lots of plants and decorations they move through.

The white splotches are water marks on the glass, no on the fish ;)

Humm, interesting, how can you tell she's a she?

I'm fairly sure none of the eggs will make it to fry, but it would be interesting if nature wins =)

Thanks!

Although I'm clueless on seeing the difference between males and females in almost all fish :D

To correct, the anal fin has no relevance respecting sex in this species, or any cory. On male livebearers (and a few other rare fish) the anal fin is modified into a gonopodium, and the female's is a normal fin. But not here.

With corys the only external difference is girth; when viewed from above, the female is noticeably wider in mature fish. Females may be slightly larger in length, all else being equal.

To your initial question, I honestly wold not want to say one way or the other (disease issue, or eggs). I would keep a close eye on this fish.

Byron.

How long is normal for holding eggs?

Behavior wise, nothing unusual going on. No labored breathing, is active, searches out food. The only difference is being quite bloated looking.

Thankyou Byron for clearing that up, I have been told that the anal fins can diagnose the sex of the cory
