Wild versus culture marble goby

The one on the right is wild river marble goby. The weight difference is about 100gm.

These are images of wild and cultured marble goby put side by side for us to make comparison. I can only detect a slide different in the angle of the mounth protrusion where the wild marble goby mouth protruded upward while the culture marble goby protruded forwar. The color differences I believe is a factor of different in water coloration. The mouth of the wild fish is also have shaper angle where else the culture fish have roundish mouth. Is this a gen factor or the wild environment factor.

The cultured fish is from my farm in Sg Petani Kedah while the wild fish is from the Tengi River in northern border of Selangor.
