Through my research on turtles, I have stumbled upon a few videos and articles that encourage you to "tame" your turtle or even tell you how to do so.
Generally, reptiles are not the most tame pets to have, and they aren't big fans of being handled, and often become stressed out from that. The general guideline to taming a turtle is said to be accustoming the turtle to your presence or making a specific sound or movement before feeding.
One of the ways I've seen when taming a turtle is to put it in a small tupperware next to you while watching a 30 minute show or so. Other ways include just visiting or even handling it more until it gets used to your presence. Provided these methods work, it seems that stress through this process is inevitable. Personally, I'd rather not try this on my turtle since it's originally a wild turtle (I am now aware of the risks posed on the wild populations by having wild turtles, as well as the increased difficulty when it comes to caring for them. I definitely realize this so this'll be the last wild turtle I keep.) and its species is mostly known as timid and "would disappear at the slightest disturbance". I would point out though that some populations of this species have been known to hand feed from tourists or residents. My turtle itself is mostly timid and also spends a good amount of time hiding (I've set up multiple hiding spots for it). Let's suppose I "tame" my turtle, that'll be especially helpful for it when I visit to feed it, since then it wouldn't instinctively hide away, and wouldn't get stressed from my visits.
My main objective with my turtle really is to provide it with a naturalistic environment and diet. I care for no more than to see it thriving happily, and personally moved on from aesthetics since I know I can't afford to give it the best home and simultaneously make it especially appealing to the human eye. What I'm trying to say is I don't really care about taming this turtle, I'm just particularly interested in whether these methods are effective and whether the stress caused through the process is really worth it.
