I was wondering if you guys have ever seen this. On one side of my biggest aquarium bass his gills are very flared out and big and the other side is normal. Here are two videos. I think you'll be able to see the different sides. He has grown the fastest by far and is now about 3.5 inch and chunky. Also, the ones in the aquarium seem to be short and fat compared to the wild ones longer and skinnier, atleast the same sized ones. Is this cuz he's in a small 30 gallon so he's growing to his container? Here are the vids:
