Speaking of egg bound females!
I once had a Petsmart zebra danio who got so eggbound (after all the males died off) that she actually ruptured both sides of her belly, had 2 HUGE red holes( I swear I could see through to the other side

), got skinny, thought she would be dead soon...and made a miraculous recovery after a few weeks! Her stripey pattern was never the same, but she healed up nicely. They are one tough fish.
