I just got a new fish (yet unnamed) last night. He seemed very
stressed last night by the change of venue from his little petstore cup to my tank. He would not stop swimming around frantically and shaking his fins around. I assumed it was just stress from the new tank so I let him be over night.
This morning he still seems very stressed out. He goes back and forth between resting on the gravel in the back of the tank to darting around and wiggling a lot. He freaks out more when I run the filter so I am not running it right now. Is this normal for moving into a new tank, or is there something else wrong? This didn't happen with my first fish.
All tank parameters are normal. I cycled the tank and conditioned the water, and tested before putting him in the tank.
Also, the new guy has a little hunchback, which I've never seen before. Does this happen?
