I finally got an offer on a possible tank upgrade for Dog. Right now she's in a 36"x18"x12" tank because I got her under kind of dire circumstances and that's all I had on hand. Someone is offering me a 48"x12"x22". I definitely want to give her more height but I feel like the 12" deep is possibly too tight? Just need some quick opinions on if I should take the offer or not.
The one you have now offers 6 more inches of floor space. If the UVB and heat isn't too strong at that height, I'd stay with what you've got. But.....there's nothing wrong with hoarding free tanks, either!
