i have a gold Severum and when i got it from the LFS it had what looked like chunks taken out of his nose ( i guess it would be called) and i thought they would kind of fill in if i kept the water good and kept him healthy but it doesnt seem to getting any better. it has been about 1.5 months. the color has improved on him alot but what i was wondering is if this part will even grow back if so is there any advice? i have heard that melafix works good on things like this i tried it a while ago and it seemed to make my water cloudy is that normal?
