Hi there,
I have kept bluetongues and shinglebacks inside and outdoors for about 10 years.
Since it’s a new environment he is most likely looking for a way out!
The best way to prevent him trying this is to provide him with plenty of hides or places undercover so he feels secure.
I’ve attached a pic of one of my tanks that shows plenty of places to explore and hide if required.
There will be times when they want to come out regardless and will climb the walls and the best things to do are to provide a good diet to promote strong bones and muscles and if possible, let him out!
Only let your bluetongue out under close supervision, in a secure place where he cannot escape or be in danger and only when he is big enough and old enough that he is not scared of you and his surrounds.
A good diet for a growing bluetongue means variety, but at a young age you can afford more protein than vegetables.
Allow your bluetongue to grow at a steady rate because if you try to grow him too fast his bones will not be strong enough to handle his bulk.
If you provide a varied diet such as a small portion of wet dog food, veggies such as carrots, peas, squash, zucchini, mushrooms, treats such as blueberries and the occasional mealworm then you should only need to dust every 2[SUP]nd[/SUP] or 3[SUP]rd[/SUP] meal and rarely when he is an adult.
If you are able to provide UV then the need for powder based supplements can be reduced due to the UV providing the Vitamin D needed to aid the absorption of calcium.
Bluetongues love snails and they are great for them! If you can provide pesticide free snails your bluey will love you!
Good luck! Bluetongues are highly underrated and make great companions if you provide a stimulating environment and a healthy diet!
And I agree with the above … a ‘boring’ bluetongue is an unloved bluetongue !
