sa enam tata adaya
nyadhad audañcanodake
tatra ksipta muhurtena
hasta-trayam avardhata
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Then, taking the fish out of the waterpot, the King threw Him in a large well. But within a moment the fish developed to the length of three cubits.
