Highlights:

• Two finite difference methods are proposed for a generalized Fisher-KPP equation.

• These methods are capable of preserving the skew-symmetry of the equation.

• These methods preserve the positivity, boundedness and monotonicity of solutions.

• These methods are solvable.

• These methods are convergent.
