Yeah, my wife named him Genius because of his reaction time to food. I will dump a hand full of massivors in the tank and the Niger cat comes out and under the feeding location before the massivors hit the ground. 10 minutes later the AUL comes out and might get stuck between the rock and the overflow, and then get stuck in the corner of the tank. Then, maybe, after 20 minutes, he's ready to feed. Then another hand full of massivors go in and the niger sucks up most of it while the AUL slowly chews on one.
