My fish, MJ, is about 3 years old and lives in a 2.5 gallon tank that is heated to 76 degrees. I do water changes weekly and try to keep it nice and clean. He normally eats about 2-4 little pellets per day, which I thought was a pretty good appetite. Then all of a sudden he lost interest in his food. Also, he has stopped swimming around. He just lays in his plant and sleeps all day.
I thought he might be constipated from all that he normally eats so I tried to feed him a piece of a pea and it immediately sunk to the bottom. He only eats food if it is RIGHT in front of him. I swear he's blind sometimes because I have to make him follow my finger to his food all the time lol.
I'm really worried so if anyone can offer some advice I would really appreciate it.
