Yet another betta question

I just wanted to make sure that the tanks and cups that people are keeping their Bettas in are covered. I am quite familiar with stories about Bettas jumping out or jumping into the tank or cup next to them and fighting the other Betta. In the end both are dead.
 
10 gallon tanks are not that expensive (I know where to get them for $10 all you need to get is some graval another $10 and the betta which is about 5) So a new betta usally costs about $25 I steal plants from the extablished tanks I have around they plants need more room as it is, they grow like weeds in my tanks as of late. Then I can steal some of the snails from the other tanks (those things like to breed and if I just need to speed up the process it not that hard to get snails to breed)

But if I did not buy the 3 bettas I did I would be 1/3 of the way to saving up to that 55 gallon tank I want to get, oh the pain of the decitions.
 
i wouldnt worry about them being right next to eachother considering i have 5 that are always right next to eachother they dont really have a choice in betta barracks.
