Hey guys I was wondering if anyone has had experience with a puffer fish and a shark together. I currently have a 300 fowlr with a 12 inch porc puffer and a 36 inch bamboo cat shark. The puffer has been acting stressed as of late, constant "glass surfing" and lack of interest in food and was thinking it could be due to stress from the shark. Water parameters are in check. The thank has about 200 lbs of live rock, several caves for the puffer as well. Any insight would be appreciated. May have to see about giving the shark to the Long Beach Aqaurium out here in California.
