Can it be done though. What temp is ideal?Not recommended, as goldfish prefer cooler water temps. Also they usually out grow most tropical community tanks.
I would say in between 5C to 40C, give or take a few degrees I guess.
Goldfish should never be kept at temps higher than 22C,
although they really should be kept at cooler temps of 18C and below.
Lol yeah they would'nt taste good.
They are just selectively bred carp If memory serves so put them on the old barby wouldn't be bad. although I would starve them for a few days first to make sure there digestive system is clear.
