Most large catfish actually dine on live food not rotten or decaying. Not saying they won't scavenge, but if you've ever owned any of the large catfish you'll know what I am saying when you have to ween them off of live onto frozen(dead) foods. That is the most awesome yarelli I've seen yet! I'm now destined to own one! I don't care if it's fish compatible or not, it will be when I'm done. They said it couldn't be done with a Jau, and I did it, now I have a new challenge(although several members have them with other fish already). Too bad they didn't get a mouth shot of that monster so we could all see his pearly whites!!!
