I havent given Joyce a bath in a long long time. Today i gave her one, and she drank a ton of water. AFter the bath i placed her back into her tank and about 5 minutes later, i noticed her "coughing". I dont know what to call it, she bearded opened her mouth and made a coughing sound. She did this about 6 times and suddenly shook violently. Like extreme shaking extremely fast. All of a sudden she stopped and coughed up a ton of water along with some green/black chunks of stuff She also has not been eating recently. Help please?
