This is my first betta, Conor. When I brought him home less than a year ago, I really did not know what I was in for. At the store, I did not know how to look for a healthy fish, and ended up buying him even though he already had the beginnings of som nasty fin rot. I had him in a 1gallon "tank" for about three weeks before my friend - who is also a betta lover - pointed out that I was doing pretty much everything wrong. If I had not changed things when I did, he probably would not have made it.
After buying him a whole 5.5 gallon setup, removing the plastic plants, buying a heater and getting into the habit of regular water changes, he started perking up pretty fast. Now, seven months later his fin regrowth is looking wonderful.
I still feel bad that my ignorance got him so sick in the first place. But after working so hard to save his life - and succeeding, I've learned so much about bettas. And I've become truly attached to my little fighter :) I hate to pick favorites, but he is my favorite!
This is Conor back in May :(
This was taken a couple of weeks ago, and his fins are growing still :)
