Well its been one week after I started the headbooster and I think theres some reluts. What do you guys think? The below pic is before and the above is after. See anything?

Kok does show improvement but I think this fish is under some stress, you might want to check the water.
One week normally is not enough time to tell the different anyway, sometimes, it just the growing process of the fish

if u do have any updates then please do share with us
