Hubby is going to buy me a larger tank (closer to 30 gallons) for my birthday on Halloween, and then I will try again with new girls. I think you're right, Shannonpwns: Once I get a bigger tank, the cambodian will probably never be allowed near other fish.
She is back in the breeder's net, for now, and ugly fish is aggressively circling it, like she's waiting for her to get out so she can take revenge.
What bothers me most about it is that Penelope's ovaries were eaten -- pretty much nothing else was touched, just the area where she would hold eggs (and I suspect she'd been egg-laden for quite some time.) I just can't get over how vindictive and evil that cambodian is.
Penelope has joined my terrarium, where at least she will live on through my plants. Circle of life, at least.
Jadablu -- I will be PM-ing you momentarily.
