Hi there Both my beardies are about a year and a half old. I keep them both in a 40 gallon tank with a basking spot with branches and forestry along with a brick below with holes big enough to hide in. They also have a uvb light. Their floor is sand and they have a water bowl. I've tried giving them greens with little to no success. They eat giant mealworms with calcium every 2 to 3 days. They're usually active but over the past couple weeks beavis stopped eating and has been sleeping all day and doesn't want to bask. Is this brumation due to winter or should I be scared?

I used to feed my lizzards bits of fresh fruit and green and shredded carrots and added to the mix was a little bone meal and a few drops of linitone for the skin. Along with live crickets. They like the hunt and they ate them like candy.

You might want to vary their diet a little more.

Well if they won't eat those I feed mine carrots and red and green peppers she loves them. Also super worms are better for them then meal woms or horn worms or Phoenix worms they are all good
