My aro will not learn by trial and error. Even after actually slapping him like you guys told me, my aro seems to think tank cleaning means escape enviroment target rich. He tries to jump out whenever I open it. He's had the lid slammed in his face, last week my hands were busy in the tank , so I used my forehead to block his jump. this time my arms were crossed so I brought them together really quick and his bony head actually bruised my forearm, big. I push him away, grab him and pull him and hold him with one hand when I work in the tank and he's loving it. The mintue I lower my guard- Wham!
