bad betta

[Kingaroo]

I have a blue betta (siamese fighting fish) who has been in my care about six months, and always seemed problem free.  I took him to a friend's house for a "play date" with her blue betta (she fish-sat while I was out of town).  I was shocked to see how much more lush and handsome her fella was than mine.  Better color, bigger fins.  Poor little Francesco looked quite pathetic in comparison.  We feed the same food in the same amount. Their jars have about the same volume of water and surface area, and are both kept out of direct sun.  Is there something more I can do for Francesco?  Vitamin drops, or the occasional dead fly?

Firstly as mystress has already implied you might  wanna stop keeping it in a jar it will survive in there but in order to thrive and get the best of your fighter , get a small tank(they don't always have to be expensive,try ebay) and make sure it has good filteration and a nice enviroment i assume your already feeding it these but they love dried blood worms.Good Luck!
