I have a very recently rescued RES who is around 8-10 years old about 6 or 7" long. I put her in her new home about four or five days ago. I am able to handle her outside her tank for shell rot treatments and feeding without any issue, but a lot of the time when I walk past her tank, or set her down to dry after treatment, she dashes in the opposite direction. In the dry tub, she scrambles at the walls until I step away (It's not a tub she can jump out of). I'm using betadine after a mild soap wash to treat the rot, which is why I set her in a plastic tub.
I tend to walk and move as slowly as possible as to not frighten her, and I am getting a mesh to wrap around her tank, but what I'm most concerned about is her bonking into the walls or potentially hitting her nose/face too much.
The tank is a 50 gallon tub. She has plenty of room to swim, and places to hide, but sometimes she does her slider thing and shoots off a little too fast. I am aware that "new" turtles (and especially this one, who hasn't had a lot of positive human contact) are generally shy and skittish, but is there anything I may be missing here? Or any advice to keep the startling to a minimum? I really appreciate it.
