I couldn't find any betta feeders. But I suppose I could do the mason jar method when I visit my parents. And it would probably be easier having a 1 or 2 gallon aquarium in my apartment. (My apartment is *tiny*.)
And I don't think my initial investment in the betta aquarium would be as much as if I got goldfish.
Yah...I think the one-gallon jobbies are about $10 with an air pump. A good investment, as they come with gravel and "plants". The Mason jar is also a good idea...
