already release them at taman tasik perdana bcoz they grew up rapidly and seems uncomfortable when 4 big turtles in a small aquarium. if want to continue keep them, need to have a pond. they live happily there. i will visit them every weekend to make sure they're in good condition. release them when they were 1 year old. now their age are 1 year and 5 months. mili is the only one that turn back to me many times when i let them go by themselves to the pond. seems that he didn't want to separate with me :( last ramadhan only three of them (mili, awan & hujan) expose themselves during visiting them at taman tasik perdana. after that they didn't expose for 3 months. and last weekend only mili & hujan expose themselves.
