We have some great big goldfish that I introduced to be "Koi"-like and look pretty but needed to be hardy and cost a lot less than Koi! They have survived all our weather including snowmaggeddon deep freezes as well as several wickedly hot summers and we have never fed them other than what they forage. Unfortunately, our tank is drying up due to lack of rain in this area and I don't want them to be stuck with no water. Catching them will be a little tricky - a dragged net would be the most effective because although there's not much water left in the tank, there are two deep spots so a net would not be feasible to use in the large space with plenty of escapes. Please let me know if you are interested in acquiring a pretty addition to your landscape and are capable of catching some. The price is negotiable depending on how many you would like to catch. There are around 20-30 (could be more), all around the same size.
