Ohh Yeah I think he's becoming healthy again !!
I bought a new half moon betta male on June 11 2012 ..
Because I didn't buy a normal aquarium yet ( normal aquarium = filter , plants and etc ) I put him into a bowl which I couldn't clean . On the 19th of June , he got a serious fin rot :(
I bought a new temporary bowl I put him into it , and it seems like he's becoming healthy again , his back fin is being renewed ! I was so worry about him ... But if I'm right and he's becoming healthy I'm sooo happy ! :):)
I hope I'll buy a "normal aquarium" for my three betta males with aquarium gatgets and plants before 2013 comes in !!
