How do I convert a mesh and curve into just a mesh? I have a cylinder that I made into a fish for a fountain ornament.

I made it out of a cylinder and a parent curve.

I want to make that into just a mesh now so I can import it into Unity.

Currently if I import the curve + cylinder mesh it doesn't work.
Just select the mesh then press alt+c. select "Mesh from Curve/Meta/Surf/Text"
