Hi! I am fairly new to reefing. I started setting up my 120 gal tank on November 2017 using canister filter, no sump! . It's almost 1 year now and my tank is looking good and healthy! I lost couple of fish and corals but most of them survived! The clownfish on my avatar is one of my first tank inhabitants 
The Sebae anemone on my avatar is about 6 months old since I first brought it home, it already ate my blue jaw triggerfish and my sohal tang and maybe couple of chromis 
It keeps getting bigger!
I have Naso Tang that's been in my tank since Thanksgiving 2017. He's never sick. Today I noticed that his tail doesn't look good. See the photo attached. Can someone please tell me why his tail became like that? any advice on how to help him get better?
All other tankmates are ok and healthy!
(CORALS: gold aussie torch, green tip torch, green welso, purple and green welso, pink hammer, purple tip-green stem hammer, blue and green sympodium, green star polyp, zoanthids,
mushroom. INVERTS: sebae anemone, pistol shrimp, hermit crabs, trochus snails, turbo snails, astrea snails, margarita snails. FISH: 1 naso tang, 3 clown fish, 1 coral beauty, 1 christmas wrasse, 1 shrimp goby, 2 pajama cardinal, 2 blue green chromis.)
Thanks
