Naso Tang not eating???

I have purchase this Naso Tang he's about 2.5 inch. He's been in my tank for about a week now. I also have 1 yellow tang 2 clownfish. Here are listed what I have used, formula one frozen, formula 2 frozen, flake, mysis shrimp, frozen krill. He bite them and split it out. I could see that the Naso Tang got skinnier. What can I used to help him eat or get him to eat? Thank all in advanced...

 

Try garlic soak or seaweed or both

 

you can try to presoak the food in saltwater and/or garlic before throwing in the tank. my chromis would spit the micro pellets back out unless i let them soak for a minute.

Also I popped in a bag of chemipure in my canister filter's media basket. it is known to help fish regain appetite by cleaning the water really well.

 

just regular garlic soak in tank water? do i chop it in piece's? thanks

 

where can I get bag of chemipure? it's reef safe?

 

I would definitely provide some dried seaweed (nori). You can either use a seaweed clip or attach the seaweed to the rocks. Tangs need the greens.

 

Never heard that one...

But to the OP. you can replicate their natural feeding by rubber banding nori onto a rock and placing it into the tank. they will usually nibble on it then.
I have had success with really hard tangs like PBT by offering actual chopped calupera or other macro algae.

 

Had to read this one twice... Ooooooooooooooooooh, Popped in a bag

 

got some seeweed veggie, he is eating it now..
