I have a large pond at Mt Barker (SA) and have Frogs/tadpoles (spotted marsh) but would desperately like some banjos as love the sound of their “bonk”. Have been trying to find banjo tadpoles for years with no success (they have always been tadpoles from spotted marsh frogs). What would be the best way to introduce banjos to my pond? I have been waiting patiently but they have not come of their own accord. Does anyone have tadpoles for sale? The marsh frogs seem quite happy and have tadpoles each year. The pond is clean, with about 18 inches (depth) of water (12ft x 8ft area) and has water plants (lilies etc.) They have protection from predators (floating mesh), plenty of surrounding vegetation and there are no fish. Any help or advice would be greatly appreciated. Am desperate to have Pobble-bonks in my pond !
