I have a 29G white cloud tank. I'm also in WA and get them all for 4 or 5 for $1. one thing I've noticed is it's very important to QT these little guys. Because they're often used as feeders, they're often low quality and carry a lot of illness. I made the mistake of not QT one batch and it killed off my entire population within a couple weeks. Next batch, I QTd with a course of seachem polygaurd and 2/3 made it through to joint the population. They are a gorgeous little fish, much better than a neon IMO.
