I've had my clarkii for about a year now. She survived my cross-country move VERY well. She got a little malnourished because all I could feed her for about a month was flake and some freeze dried stuff. When I got to Houston I got her on a good variety again, but the day after introducing the new variety, she started acting strange. There aren't any ich spots on her so it's not that. She is hanging out near the top of the tank acting lethargic. The day after she ate the food, she started swimming into things too. I've never seen her act this way. She's a real spitfire. She is sharing a 5 gallon holding tank (for now) with my bi-color blenny. For the past 2 months, they've gotten along in there. It was the only place I could keep them while I was visiting family for Christmas. I am waiting for my 12 gallon to finish cycling so I can separate the 2. Her bottom fins do get a little shredded by the blenny, but she asks for it most of the time and that's nothing new. They've gotten along for a year since I bought the 2 together. Could the clarkii be scared of the blenny now??? They're about the same size if they were the same shape. My clarkii doesn't really have any interest in food anymore either. The only other thing I could think of is that she does tend to try to inhale the food before it hits the water which could've caused her to gulp air. Any ideas on what could be wrong with her???? I'd appreciate any help.
