Wow! John, It reminds me of my dog. We picked him up off the sidewalk only a few minutes after he was born. He's never been around dogs. He's only lived with 5 humans and a cat all his life. When we rub his tummy he gives out a long low growl. I guess that's the closest he can come to purring (poor confused mutt). I don't know of any reports on cross species behavior mimicry in fish. You might want to address this to Cichlid-L. The real pros might know more. Mike Wise John McCrone wrote: > I put a pair of agassizi in a community tank with four keyhole cichlids.
