Input: This is not me. This is truly for my cousin who's too young to have a Reddit account.

Tl;Dr Is my cousin Dominick (11) the asshole for getting into a fight with his mom because she doesn't want to get an appropriate sized tank for his beardie, because she says he doesn't need it (but does)?

His mom got him a bearded dragon (adult, super tame, former breeder, lemon yellow, 4 years old) for his birthday. He's 11 so obviously he doesn't have money to take care of him but it's still his pet, he just gets help from his mom for buying the things that the beardie needs.

With it she bought a 20 gallon long tank. This is way too small for a 16 inch beardie.

Herbert is well taken care of. They live in AZ so the little guy gets to hang out outside while he's at school in a secured backyard habitat (chicken wire, a boxy thing in the ground so if he digs he can't escape, even has a camera that tracks movement since beardies don't move much, and has a door thing so he can get inside) The rest of the time he's either in his cage or hanging out with my cousin.

His mom buys Herbert's food and does everything else pretty well for him, including taking my cousin to the store often to buy him fresh vegetables and fruits that are safe for beardies, buying the necessary vitamins for him, buying a setup for dubia roaches to feed to him, and literally buying clothes for him. Also takes him to a vet whenever needed.

She says he won't need a bigger cage because he spends a lot of time outside. However he's obviously uncomfortable with the tank because he wall surfs and taps on the glass, there isn't much room for him, it's a basking rock cave thing,   food, hammock and a wood branch thing.

They can afford a large tank easily and have plenty of room to do so. My aunt has a really good job and makes 120k per year, big house and   central air lol. She just says it's fine apparently.

My cousin got in a fight with her because she says Herbert doesn't need a big tank, but even the vet said she should and my cousin does too. He has plenty of space in his room for it and just needs his mom to buy it.

yelling at my mom for lying about getting my Bearded Dragon a bigger tank
