I finally bought a turtle dock....the ones with the suction cups, I used to use a big rock, that my turtles loved, and they seemed to bask a good amount. I just bought a turtle dock that most people seem to have here on this site, and I haven't seen them get on it once. Do they just need time to adjust? I'm so tempted to put the rock back!!! But it takes up so much room

I also added a plant, and a nice background, so it's kind of a new environment for them. One more question.....how long is too long for a turtle to not eat anything? One of my turtles isn't eating, my other one is.
