my new fish has her fins plitting on her tail and the top fin. does anyone know what could be causing this? i'm thinking its either my other (bigger) fish...which i havent seen him pick on her, or its the rocks in the tank, maybe she's rubbing up against them. could stress cause it? will it heel back to normal? i'm just worried about her, i dont want her to be sick or anything. thanks in advance for the replies
here is a link to some pics of her...
