ok so looking to keep my turtles not bored and maybe less destructive. rearranging stuff last about a week. then they start moving things themselves. yesterday everything with a suction cup holding it to the wall was removed and free floating. they started this weekend while we were out of town digging up all the fake plants.
things i've tried so far, a new decor item once a month, at least sometimes more. a floating plastic golf ball. that lasted the first few days it was put in. now it's left alone. shooter marbles, they lasted till they got them so stuck in the sand they won't roll anymore. they ignore the fish. >.> and crayfish has a decent hiding spot. they can't get to her. but they know she's there. but they got bored trying to get her a week after we got the tank rearranged as it is now.
anyone else got any ideas?
turtle size is 3 tiny babies, less than 2" tank size 75gallon.
