Hey guys I got my betta from petvalu 4 days ago now and he is missing a large chunk of his tail and has virtually no appetite. On day 2 he tried one pellet and promptly spit it out and has shown no interest in pellets, on day 3 I got his to eat a little bit of freeze dried blood worms. He is in a gallon cube right now till I get my 5 gallon in a couple days. He mostly just lays on his leaf unless someone is walking past his tank. Would salt baths help him?
