Any additional info you would like to share.... Including anything different that you have done/not done.

Let's get to the bottom of this. Any of the above info that is questionable to you is pertinent to keeping a happy/healthy tank/wallet.

 

tank is to young to support that species fish of for very long they need pods to eat and lots of them tank needs lots of rockwork

 

Well, my first guess would be that it is probably starving to death, which is the cause of probably 99% of mandarin deaths. Can you tell me what it's belly looks like? How is your pod population?
I really doubt the lights had anything to do with it. Mandarins are actually pretty hardy fish once you get past their difficult diet requirements. But those nitrites do scare me. They can be toxic at any amount. Have you tested the water for them BEFORE you add to the tank? Did you cycle the tank properly or add anything like rock or even shells lately?
The only other things I would suggest is to go slow and do a lot of research. That tank is pretty heavily stocked for being just 3 1/2 months old. And you need to get a full and proper test kit asap! I wouldn't be adding livestock until I knew that ALL levels were good.

 

well ill get pods right away and get test kits gradually dont got the money to go but 5 15$ test kits right away evrything els in my tank looks great hes only bad one :/
