Thanks for the link AD. I'm getting more and more interested in trying one out when we get our pond done. Looks like a fun and productive project. A few quick questions, I believe the benefits are isolating fish to both avoid predation and feed in solitary. Are there other advantages I'm not thinking of? Also, is there a problem when the water temps heat up and most of the fish would take to deeper water, but your caged fish are unable to do that?
