Another new goldfish model.

A new integrable (indeed, solvable) model of goldfish type is identified, and some of its properties are discussed. Its Newtonian equations of motion read as follows: where c, c, and c are arbitrary constants, z ≡ z(t) are the N dependent variables, N is an arbitrary positive number (N > 1), t is the independent variable ('time') and the dots indicate time-differentiations.
