This is a fun idea, but for those who are interested in actually rescuing a betta for this competition the timing might be kind of bad. I know for me personally I couldn't get a new sick betta because I am leaving for a week for the USA Thanksgiving holiday. If you ever decide to do this again, I would definitely be interested. :)
I mean you don't have to rescue a Betta specifically for the competition, you could have gotten it awhile back, but as long as your rescue Betta isn't in optimum health (meaning that their fins still have room for improvement - growth etc) you can enter. You just need to have taken a photo the night before or on the day that the competition starts, and another photo the day before or on the day the competition starts. You don't need to rescue another Betta! XD
Oh I know, but I only have the two fish, and neither of them have had any fin problems. And I do want another fish, but I don't think sick fish like traveling 400 miles. lol. So I will just have to wait for the next competition!
I want to... but you know, is not that easy. Even if my fiance would approve of a new animal in the house it is way to near to holidays for me to be bale to give a sick animal the attention it needs, since I will be leaving.
