Ok, so I have had my pacmans for a week now and I have never seen them get in their water bowl once. How long before they will start using this thing on their own? I usually set them in it every night just trying to remind them it's there and when I do.. they sit there for a while and use the bathroom in it if they can and they appear to enjoy it.

Their hides and water bowl is on opposite sides of the tank, you think I should move them closer? The tanks are only 5.5gals. Have you guys ever had pacman frogs that never used the water bowl on their own? I've seen some tanks on youtube without one at all, but that just doesn't seem right, I feel they should atleast have the option..
