Many people state that if you have a hide on the warm side of your tank then you should have the same on the cold side? Is it necessary? I have a fairly large tank for each of my snakes, they spend most of their time in their hides which are on top of the under tank heat pad. And occasionally they'll come out and explorer. I keep the water bowl on the cool side to help maintain its cool. Never had any issues but now wondering if I should invest in another hide, but how do owners with snake racks pull it off?

Also in terms of exposure, my larger snake is kinda a centerpiece in the living room, has branches and trees that cover up some of the tank but for most of the part it's pretty exposed, I've read many owners cover their tank sides to make the snake feel more safe. Is that also necessary?

Like I said I feel like my snakes seem happy, eat well, shed well... But wondering if they'll be even happier if I adjust.

Thanks
