Ok, there are several things disturbing me about this thread. To start off, you occasionally find a CT or DTs, or even a HM in stores, but they're usually bred poorly and are sick, many times doomed to die. Even if you find one, it's still a store, you still have to pay for it.
Secondly, if you have no job, then I'm assuming that the money in your account came from your parents, possibly an allowance, in which case, it's theirs, right? If they don't let you 'spend money on fish' like you said, how in the world are you supporting the betta you had before? I mean, granted, they aren't really all that expensive to keep healthy, but it had to be coming from somewhere.
Thirdly, if saving up for a video game is more important to you than saving up for a more expensive fish, then the fish is obviously not *that* important to you. Many times rarer fish are more delicate, which might end up costing you more in the long run. And, rare fish are more than likely going to be more than $10-if this is all you are willing to spend, then you might as well settle for an 'ugly' VT.
Willywonka, please don't encourage people who aren't experienced to breed bettas. This is scary, and this is why we are so overrun with the torture of these fish.
All in all, if you won't or can't get a job right now, and your mom isn't willing to support a pet, then I wouldn't advise trying to get one. All it will end up with is the slow death of a poor betta.
