Porcupine puffer

[fisherpayton]

I have recently purchased a porcupine puffer fish (5 days ago) and so far I have attempted to feed frozen mysis, half shell clams but so far he has not yet attmpeted to eat and within 24 hours he has darkened in colour above his head and body, and he now sits at the bottom of the tank. I just note I have also freshwater dipped him

Pictures may also help, but a short video can help me judge the puffers respiration rate.

How big is the puffer?
Any white stringy poo?
Puffers are known for being extremely finicky, and can take a while to get eating.

The most common reason for a porc not to eat is internal parasites, also not recognizing dead food. I would offer him some live ghost shrimp, and if they don't eat them, immediately treat with general cure.
