This platy i'm having problems with is named El Stupido. From day one he's been following my betta, and was unafraid of him (the other three are fine and stay away from him, usually). From day two, El Stupido's been nipping at my betta. Now, it's day three or four (cant remember)... My betta hates him. He's constantly sneaking behind him, edges for him, just to get a taste of his fins. My betta is miserable. I lost the receipt for petsmart. Do I take El Stupido back? Will they take him? Will his other platy friends mind? Will the other platys do what El Stupido does and nip too? Yes, El Stupido tried nipping at his friends too, but he found that he prefers my betta, so he only nips him now. He's a cannibal.
My betta is ironically named Salmon, btw.
