achilles
 

gone

What else have you tried to feed him?

mices ,krill everything soaked in garlic, flake , pellets

When I got my achilles he didn't eat anything for over 2 weeks. I eventually got him to eat Ocean Nutrition Red Algae Sheets by wrapping them around small rocks with elastic bands.

He now eats nori, mysis and frozen angel food.

What is the size of your tank? What is the size of the fish
and what species are the other larger fish in the tank?

thank you i will try this

100g scopas tang,clown tang,regal tang,2 tomatoe clows ,achilles tang 5-6 inches relative to everything in tank

Sal you have several problems.
Your tank is too small to accommodate one of the tangs you have chosen let alone three. Your newest naso is stressed out.
A clown tang is extremely vicious and is almost impossible to keep even by expert tang keepers. Naso's are also difficult but not impossible.

You need to get rid of, at the minimum, two of them.

In the short term move the naso to your quarantine tank. Put some rockwork in so that he can hid and feel safe.
Keep the lights off or dim.
Do not approach the tank except to feed her. You are adding to the stress.
Feed brown alge which is the natural food of this species instead of green algae.
Try soaking the algae and all other food with garlic extract (not juice) and selcon vitamins. Try also a little mysis and worms.

IME, the fish is stressed and will not eat in your main tank and therefore is starving.
It is also possible if this tang is from the Philippines or Indonesia where the use of cyanide is rampant, that it is dying a slow death from cyanide.

Thank you

I would go with sheets of algae or nori possibly with a few drops of garlic on it. Best case scenario is to sell it to me cause you know when it came in we were all drooling over it:biggrin: Just kidding I really hope it pulls through for you!

well your fish is the 3-6-9 fish
first 3 weeks is very touch and go for being in your tank, lots ofthem don't make it
next is the 6 week mark is a important one too getting use to the tank and tryingto keep the ICK down.
then the 9 week mark after the 9 week mark the fis hwill have a good life , if the tank conditions are good
