At one point it seemed he was so mad, that he started thrashing at the bottem of the tank strong enough to push all the rocks aside! Took a few minutes, but Flo eventually calmed down. Could his tank be too crowded? (Pic as my avatar displays full tank, decor and Flo!)
If he's anything like my male, he doesn't like change, and my male really doesn't handle it well. He doesn't thrash around, but he goes to a corner and sulks. He starts biting his tail and hides a lot more. When I upgraded his 3 gallon to his 5 gallon, I had to try to place his decorations in the almost same spot as they were in the old tank. The only difference was more space, and his thermometer wasn't as close to the surface as it had been before. It threw him for a loop. He bit his tail for a few days and "stalked" his thermometer by pacing back and forth behind it and then would stare at it for long periods of time. He used to sleep on top of it right next to the surface in his old tank, and with its new placement, he couldn't do that. But eventually, he calmed down and found that he could sleep on top of his plant leaves near the surface, and that was even better than the thermometer.
