Act very quickly. Water parameters must be off or he is very ill. Check everything immediately. Are there any signs of external injury?

[xDopeBoY]

not really any signs. the other fishes are bright. and hes a darker than they are. hes still very weak :[

Well are your water parameters good?

Check water parameters and perform water changes. Puffers can be sensitive to climbing nitrates and will not do well cycling a tank. How long has he been in the tank and how long has the tank been set up? If he doesn't perk up a little after a water change you may be out of luck, most puffers are still wild caught and sometimes just don't pull thru the capture, transport and new home situations they have to go thru.
