Hello everyone We need your help urgently. My cleaner shrimp, which has been with me for 40 days and has changed its shell once, started acting like it was frozen after adding a fireshrimp to it today. He's alive, his little mouth is moving, but he looks like he's completely frozen. I even took it in my hand, it bounced a little and I took it apart. There is no change in all other fish and corals. Why might he have done this? Also, since Bluetang has blue spots, I gave garlic food along with Seachem Stressguard and garlic with carlics food. It must have eaten all the fish, could it have harmed it?
