plump fish? and torn tail.

[iLikeBetta808]

whenever i look at betta pictures, the betta looks plump, like they have some meat on them. and when i look at mine, it's just skinny looking. :/
guess i have to buy more food the next time i go back to petco.

also, my fish's tail got a little torn this morning. idk how tho x_x
so i treated him right away. changed his water and added aq. salt and stress coat. the black edges were almost gone, now i have to treat him again :/
