Yes~ i had tested my tank, everything is fine.
The lemonpeel is just not eating in my tank~ i brought it back and it is loss to a starfish not because of the fish is sick.
Other then the crown, the tang is having whitespot but it seems to be less then before...about 10 now
Don't have a DC on hand now so i can't post some picture. It is looking worst then before...just floating on the surface of the water. I will go purchase the stuff i need to treat the fish asap...but i got work again tomorrow....don't think any FS is still open after 6pm...
