Hi guys. Went to my local fish store today. It's not a bad store. They had a group of new German Blue Rams being acclimated. They were a good size. Not babies by any means. They were in a tank with a group of Amano Shrimp. One of the Rams looked sick. Was sill alive but couldn't swim properly or fight back and was being constantly attacked by two Amano's. They were nipping it's tail, fins and body really aggressively. The other Amano's weren't interested though. Is it normal for Amano's to attack sick fish?
