I have just had a call from the girlfriend to tell me that the betta I bought yesterday has died, It had wedged itself into a small hole in one of our rocks and could have been there most of the day until she got home from work. When she removed the fish from the rock it seemed to be alive still but only lasted a couple of hours at most before passing away. Is this normal behaviour for a new fish or did I just get the stupid one of the bunch? I have decided now that I will remove these rocks incase the same thing happens again.
