The pics are a bit blurry but he looks beautiful! Check your camera to see if there's a setting for taking close up shots. The icon should be a lilttle flower. It will help you get better shots. I find that external light helps too.
It is rude to tell someone thier water is dirty,
Incandescant lights can make a yellow dingy overcast in photos, and also he could have tannins in the water.
Beautiful fish, you could aslo take the pics a bit farther off then crop them small around the fish.
1. he has live plants,
I can change my water 100% and rise off the plants, yet still they make the water look a little dirty,
2. If you don't have anything nice to say then don't say anything at all.
It looks clean in the vid to me.
If it were that dirty, you would definitely see derbis resting on the flat areas.
Knocking someone else's bettas or tanks is very rude though point blank.
It would have been different if you asked when was the last water change, but from what I can see, it doesn't look dirty.
I have the same issue with lighting, in the room where my Fishy the walls are painted a cream yellow-ish color and it makes things look yellow.
The camera I use is a plain point & shoot, it doesn't do the focusing that I'm used to in a manual Single Lens Reflex camera, plus Mr Fishy keeps darting about wondering what I'm doing. Blurry pictures abound. Haha.
