Hi, I'm new to the forum and have a largemouth bass in a 200 gal tank currently. He was recently moved from his old tank about a week ago, to the bigger size tank. In his old tank he would eat voraciously, shrimp, fish fillets, crayfish, anything. So far in his new tank he's been picky and only eaten a few shiners and nightcrawlers. He also has the beginnings of hole in the head disease which I am treating him for. Is the lack of appetite most likely from stress or something more serious?
