You want to place the sprite AFTER anything that will move the fish (i.e PositionEntity, MoveEntity or TranslateEntity etc), and before UPDATEWORLD and RENDERWORLD.
Also, if the sprite is too close to the fish mesh, it may be covered up by certain polygons of the fish mesh i.e. Clipping.
As Stevie G says, try adding a bit to the 'Y' position of the fish (this is the vertical) if you still have no luck, post some of your code here :)
