Ok so I had a RTC/TSN hybrid (8-10 in) in a 75 gallon with a couple of pacu. I moved the pacu to my 1100 gallon pond as they outgrew the tank. Since I moved the pacu, my catfish hasn't eaten. When I moved the first pacu he was fine and acted normal, but when i moved the last one about a week ago he just stopped eating. I feed them tilapia. I can't really move the pacus back inside from the pond. No spots, sores, or any sign of illness or infection on him and water is 79F. If anyone knows what to do I would greatly appreciate suggestions. I wasn't worried at first but it's almost been a week. Thanks.
