I found my Mom's old Kritter Keeper that she used to put her Chinchilla in, like, 20 or more years ago. 2 years ago, my uncle put a water snake in it for like, 3 hours at most (cause I wanted to look at it xD). It's been sitting in my Grandma's garage since then and then got moved to our house when she moved out of her house. It had dirt in it and is kinda old looking, but I washed it out anyway.
I figured out that it's a 3 gallon, and aside from a few marks in the plastic from just being old, it's in good condition, so I wondered if it would be safe to put my betta in it?
Thanks for any help! :)
