My friend has some 6-8 inch goldfish that he has kept indoors during the colder months. He recently set up his pond, does not use a heater, I do not have the temp at the moment ill get that from him, but how long would you keep the goldfish in the rubbermaid tub? They got pretty big so he put them into a tank that was set at 78 degrees and they have been in that for 5 or 6 months. Would it be ok to just take them out of the tank, toss them into the tub and leave them for a day or two with a filter and airstone? They right into pond? Thanks
