My ghost knife has always had this weird bump on his side - it almost looks like a pimple. He's been fine though - I've had him for 6 months or so. I came back from school thursday and gave him a large (for his size) shrimp. Since then he's been acting weird - I assumed that he was full and not needing food. But he hasn't eaten since Thursday night, and I was worried. I came in and moved him, and looked at him today. THe pimple like thing was way, way smaller. I'm not sure what I can do if there's something wrong with his anatomy except pray, but I have treated him in very very small doses with melafix.
