Perhaps the fish and the crab can take him

Thanks for the comments and another great tip adl thanks.

The fish body was done with the create poly tool followed by the split poly tool in logical places, then some pushing and pulling, then simplifying the mesh and tidying it up before mirroring it to create the whole. I initially did the same for the tail but I wasn't happy with it so I started with the body and then extruded the fin and tail afterwards. One smoothing iteration then got it smooth as I wanted it and I softened the mirrored joint edge to stop it being a visible line. It's not a very remarkable model but I think it is coming on OK.
