Mr. Fishy is my first betta fish and first fish in general. He has always been active and happy most days. He ate like a pig. He loved his bloodworms and only ate them and nothing else. About a week and a half ago he stopped eating. Hasn't eaten a thing since. I then observed him for a few days hoping it was just a temporary thing. So at day four i decided to give him the betta care medicine that i got at petco. I did that for about three days. Seprerated him in a small container so he could reach the top for air easy because he has gotten weak by then. Then put him in the second container ive ever had for him. He has since turned slightly white. His fins are shrinking. At first they had little bumps at the bottom but i think that was because the tetras i had in with him were nipping at his fins. I removed them the second i noticed it. He gets agitated from time to time throughout the day where he darts from side to side then just sinks to the bottom and doesnt move for a really long time. Im just wondering what his condition is and how much longer he has. Just trying to make his passing as comfortable as possible. Every condition ive read doesnt fit at all.
