My name is Debbie and I have had gold fish for a year. I bought two last year as I wanted to care for something besides myself. One died recently. I then bought two others and one died two days after buying it. My Dad and his lady friend came round and we discovered that the other fish caused his death. I was given another fish free of charge to replace the one that died and the other new fish was just chasing him all the while and trying to bite him. and he has really stressed the fish out. The other one must have died as a result of this treatment. Dad has taken the rogue fish away. The fish is very stressed and is not moving around much. Do I buy another fish so that he isn't lonely or do I just stick to him. I can't do anything until he stops being stressed.
Any advice is welcomed.
