thanks for your response, very helpful.
just to clarify: mostly what i'd like to know is whether or not the fish will instinctively attack your hand every time you stick it in no matter what, or if they are capable of learning and remembering not to attack my hand.
From my experience, they can definitely learn not to attack you. For a lot of them, though, the thought never even seems to cross their mind... my oscar has never bitten me except when mistaking my thumb for food
They just get used to seeing you and know you're not a threat. Only the most aggressive are going to attack, I'd say.
