As you may have guessed, I am very frustrated with my poor fish right now. He is in a four gallon tank by himself with a few plastic plants and I have been doing water changes every two weeks, and although the water is not cycled it is at a decently good quality. I know not having it cycled is bad, but I have some plants I am going to move in to cycle the tank.
However, despite my best attempts to keep this fish healthy I just discovered that he has bit two chunks out of his tail and looks overall less healthy then he did when I got him. I purchased him from a petco because he was missing some small chunks from his fins but otherwise looked healthy, and I thought with some tender loving care his fins would grow back and he would be happy.
Yet the exact opposite happened. He is still stressed and is looking bad. I recently had a fish die from fin rot which I did not catch in time, so I really want to get ahead of whatever is wrong with the fish/tank. Any suggestions on how to fix this? I have some Indian Almond leaves, but will that solve the problem, or only temporarily make the fish feel better?
Thanks so so so much
Also, how often should I change the water in the four gallon tank?
