HI,
I had some adult sea horses probably WC, that were being difficult and asked the LPS I bought them from if I could let them come back for a while to start feeding, he said sure after a couple days they perked up and started feeding.
My guess is your fish was damaged goods when you bough him no way to know whats causing his healthy change so suddenly, See if your LPS will work with you, and take some water for testing see what off, he may perc up enough to save his life in his bigger system. Many experts reccomend putting fish on layaway for a week or two at the LPS that way if they are new they will get sick in his tank, its to easy for LPS to say hey its your tank that killed him, when in reality it was the shipping and they noticed he was off and pushed it out the door on you to prevent losses, many LPS lose 50 % off their recent shippments in their tanks.
It sure happend fast, is there any coral or fish that may be toxic most puffers are nippers I don't care for them in my tanks they are very aggresive towards everything and tend to eat alot .
Good Luck.
My tanks were driven me nuts till I added a reforgium and a sump with a dsb this fixed alot of problems and was cheep all I needed was a overflow skimmer and a simple return pump used a cheep show box for the alage.
water quality went up, I don't like stars in my dsb or crabs only snails and worms.

this is a bargin basement reforgum but it works. and adds water to the column the lava rock needs to be soaked for a day or two or it will stain the water and if it becomes clogged or dirty if your over feeding the same thing can happen with live rock thats why they reccomend blowing it off with a turkey baister. Everything that touches water has to be new and never seen soap so buy your own turker baister and keep it with your tank supplies you don't want to have a slow die off cause you added some cleaning products (traces of dishwashing soap) to the water column

I also rinse all filter pads, and canisters weekly they only seem to filter particles and don't add much bilogical benafits they seem collect most deitris and calcium carbonate at the end of the week they are pretty ripe they can become nitrate generators if not kept rinsed, I never toss the pads I only rinse..
