Solidworks for model

The solidworks model was made for the fish was made with an excessive number of lofts. At this point I dont know how big the tank will be so getting the size right will be hard. I know that it is easy to scale it down in the 3d printing program. I will have to make the fish within 2 halves and a hole in each half for a weight. I modelled half the fish then mirrored the half then cut extruded the original part.
