Clownfish tail turned transparent'ish

[Elton99]

Curious to whats going on with my clownfish
Just got this guy few months ago eveything was great. I moved him to a new tank setup. Got busy with work and slacked on watee changes
I know im awful and feel really bad for that. I almost got out of the hobby. The water was QUITE dirty. I apolpgoze to the fish and the readers.

But can anyone please help me or tell me whats going on? His tail i believe use to be solid white? You can see in the photo its slightly redish / transparent . Nothing has changed in the past week its remained like this.
Can anyone please help ?
Ive put him in a clean tank and would love to hear feedback on what this is

Can you post a better pic? Some clowns will
Change color as they age

To be honest this fish is prolly quite old and i dont remember this transparent spot on the tail. If you look at the image from a little far back you can see the tail use to be brilliant white
Now its rather transparent whiteish. With maybe a redish hue
Hasnt spread , got worse or better
But the water was dirty
Amonia poisoning? The fish is still eating quite well
