Last night I taught him a new trick

. I had my hand half way up the tank in an o shape, put a few bloodworms inside and in no time he came up to it and starting crawling around my arm trying to find the bloodworms. Eventually he figured out that going through my hand = where the food is.
so now I have a NOCTURNAL by nature catfish that handfeeds, is diurnal, and will swim through hoops. What next!!!
