I was at my lfs
today looking to buy a bn pleco when I came across a big common goldfish in a small tank. The fish looked depressed and i knew it would probably never get a new home due to its size. I asked a employee wether it could go in my pond but he said it was too cold. I bought it anyway as I could not help myself. It is now in my 300l tropical tank wich is at 23c. I really want to put it in my pond as it seems really active and happy now. Would it be ok or is it to cold? The pond is at 7c and the temp will continue to fall. The fish looks abit malnourished and thin. It took food straight away and has a good appetite. He is about 6 inches long.
