Congrats nyoder
First time when I tried to feed my RES she was so scared and went to hiding. So I left the lettuce to the tank. And so whole week.
Second time instead the lettuce she bite my finger thinking "Hmm thats one fat earthworm". Again...I left the food to the tank everyday for the next week.
Third time I took chopsticks, took one shrimp and I gave it to her like that...instead the shrimp she attacked the chopsticks close to my fingers. Then I realized she was afraid my hand, but why? Was it something from the past that scared her, but what? So for the whole next month I patiently everyday took her out from the tank, put her another container and gave her food and one day she just looked to me stretched her neck out then was thinking "should I take the lettuce or not" and then gently reached and took the mouthful lettuce.
Right now she's been with me three months and I am able to feed her in my hand and she doesn't afraid me or bite me anymore. I almost forgot that I really don't know how old my RES is, because I found her wodering around in the autumn.
