Well she hasn't reappeared and my tank params are back down to 0,0,10. At least I have a bunch of pics and my memories of the monster shrimp. I don't think I'll get any more. No sense in killing the poor guys and I don't really know why they died in the first place.
If you go to my user page, I have an album with pics of her in it. I got her a while back. I think she only lived maybe a month. Invertabrates just die in my tank. I'm not sure why. So no more for me. She never reappeared so I know she's gone.
