Ok, so my octopus still isn't eating. he wasn't even interested in his crab today I did notice that the tip of one of his arms was white, however, suggesting that there was some skin trauma to the very tip. He may have stuck the tip of his arm up one of the holes in my outflow diffuser. Does anyone know if that might affect his behavior? I've heard that octos injured in captivity don't have a high survival rate due to infection, so I'm hoping it's not as seroius as that, but I can't help but wonder with his recent aversion to food.
