Care

Thread-leaved water-crowfoot is a widespread water buttercup of slow streams, rivers, ponds, lakes, drainage ditches and dune slacks, found up to about 3,000 m (even in lakes near Mount Everest). Its underwater leaves are split into fine threads, shorter than those of river water-crowfoot, and it bears white, yellow-centred flowers above the water. It is a cool-water plant for ponds and coldwater tanks and is unlikely to thrive in heated tanks. Water figures are our estimate, not from the sources.

Breeding

Plant stem pieces, which root at the nodes; it also sets seed. It may be annual or perennial.

Compatibility and tank mates

Grazed by goldfish and koi. Good cover for native fish and invertebrates. Not a tropical plant.
