Terrible news guys, my gold fish passed today.. This is devastating for me as I was going to prepare a QT tank for him, wen I saw him dead and apparently the other fish must have been a bit hungry....... Examined him upclose and saw no possible causes of death, accept for one side of his stomach bulging out. He has maybe reached his lifespan, as the pet store from which I bought him from is known for selling old fishes. Felling sad.
