Hopefully someone can give you a better answer... This is my first batch, I didn't know mine were carrying eggs until I saw them on the glass. I've noticed a few of them have looked... chubbier? More rounded in the chest area. They've grown a lot lately, so I kinda just thoughts that's all it was.
I had originally planned to let nature take its course, and not take any drastic effort to save any babies. Then I saw cory eggs on the glass, and ran out to get a breeder box. Haha. And at least a few were already eaten in the half hour it took me to run out. The rest, I scraped off the glass, and dropped a few in the tank in the process, but still ended up with close to 50. I wonder of that was all from one female, or multiples?
Also, how do you tell the difference between the bronze and emeralds? All the ones I've seen marked as emerald look exactly like the bronze. Maybe they were mis-marked?
