mabe train him to do something useful like when you put cup in water he swims into it so you dont have to stress him out during cleaning/100%water change time. i am currently training Pavo. i am teaching him to follow my finger right now then i will work on the getting into cup thing. i can update you if you want?
i have already taught him to jump and follow my finger but i only got him on 2014,5,13 LOL
