I have a 450-500 gallon indoor pond with 4 comets in it that are about 5-7 inches in length. I also have a 10 gallon tank with a about 3 inch fantail in it. I want to more the fantail into the indoor pond, but i have some concerns. The fantail is still not bit enough to eat the pellets I feed the comets but i could just buy smaller pellets. Is it safe for me to move this fantail in the pond with the comets? What kind of temperatures can a fantail endure? Is a fantail as hardy as my Comets?
