porcupine pufferfish weird behavior

[Noob_Sam]

Hello guys,

I bought this porcupine pufferfish 3 days ago. He was at my LFS for around 2 months and was on a dry krill (Tetra brand) diet. The water is medicated thus there was no need for me to QT him. At first, he was very energetic swimming across the tank, coming up to me when I approached the tank. But since yesterday he found a place on the live rock to nap all day. I understand they are nocturnal but he didn't bother coming up to eat.

I fed him today after I put my hand in the tank and showed him the food. He took a bite. Everyone in the tank is a long-member and all are doing well.

I am feeding him frozen shrimp for Costco and will include a picture. I am just worried about the sudden change of behavior.

Water parameters-

Salinity - 1.024
Ph- 7.9
Ammonia- 0
Nitrite- 0
Nitrate - 5.0

Hello,
Yes. My LFS uses copper and prazipro in their water for saltwater fish.
