Depressed Beta Fish! Please help me!
I have had my beta fish for almost a year. He seems depressed. I bought him a castle but he didnÂt swim in it or anything. He just sat on the top of one of leaves and blew bubbles. He looks like heÂs playing dead all the time! HeÂs skinny and seems to be swimming a little sideways. Last night I took out the castle and put in to little plants. I noticed that the stringy ends of his fin I guessÂ3 of them fell off. IÂm sorry thatÂs the best way I can describe them. He sank to the bottom and hasnÂt moved much. His tank is a little under a gallon and there is a little light on top. His water is always room temperature and I change half of it once a week or every two weeks. IÂm afraid to put a filter in the water and stress the fish out. What do I do!!!! Someone please help me! IÂm afraid when I come home from work heÂll be dead.
