Probably should have walked away. Didn't. Was in a pet store where the rodents, snakes and dogs looked okay but the birds and tanks were terrible. There was a lonely yellow gorg in an algae filled tank. I bought it for $30. It is withdrawn and shedding. The woman said they just did a big water change because someone had dropped something in the tank. Anyway -- wish me luck trying to get this guy in my tank without adding any of their water and not exposing it to air....
