Well, my female Golden Wonder was returned to the lfs today. I came home to find her with a mouth full of Oto Cat...and she wasn't letting go, literally had to pull the Oto from her mouth. The Oto seems to be okay after an hour or more of hiding is now out and about a little so my fingers are crossed. I'm watching the male Golden Wonder like a hawk but he is smaller & seems less aggressive so far, the female terrorized the heck out of him also. At first she would just chase him but after a few days she would literally put him in the corner of the tank under the bottom of the sponge filter.

I feel bad I couldn't keep her, really liked the inquisitive personality.
