Just an off topic:

You know why those Betta males are in small cups of water? Because they fight and will KILL each other if kept together in a huge naturalistic tank. It's only temporary housing, and they are fine. They live in very small puddles in rice paddies in Thailand and other asian countries. The majority of breeders I have seen keep theirs in small jars all lined up on walls. It's definitely not cruel..

My first Ball female, I kept in too big of a tub. It was too tall and didn't offer much protection to her. I switched her to a 41qt tub in a rack and now she shoots out of the tub on feeding day for her mice. She's also breeding every single time I've put her mate in with her, and developing nice-sized follicles. If she wasn't happy, she wouldn't do any of this and would just curl up in the corner and die..
