I purchased a betta fish months ago from a local pet store. I used to have him in a bowl, however have since upgraded to a five gallon tank that is heated and treated with water conditioner. The tank also has plenty of gravel and a plant. The betta thrived. I recently noticed a hole in his fin and a dull, grey looking spot near his head and on the side of his body. It looked like fin rot and a fungal infection. I started treating with pimafix and melafix. I noticed a new symptom recently. He trys to hide or bury himself in the rocks. This third symptom is confusing me. I know bettas will do this if they have a parasite or ich, however he does not look like he's been dusted in gold or have multiple white spots. His appetite is still strong to my surprise. None of these symptoms point to one thing and I'm losing my mind trying to figure out how to treat it. Any ideas? Thank you. Also I did put some aquarium salt in as well. I will try to attach an image. There is a spot near his head then the two on his side.
Answer Hi Wilson,
I assume that you are doing regular water changes? You should be changing at least 25% of his water once a week, every week.
One unfortunate possibility is that he just might be getting old. Bettas do not live very long.
I am an expert on cichlid fishes, particularly New World cichlids. My broader expertise includes the behavior, ecology and reproduction of fishes in general. (I am NOT an expert on Goldfish). Please do not use abbreviations, such as "my GT has a swollen eye" because I don't know what a "GT" is. The more clearly you can explain your question, the better chance I have of understanding what it is that you seek. I keep fishes both as a scientist and as a hobbyist and I currently maintain about 140 aquariums.
I am an Associate Professor at the California State University, Sacramento in the Department of Biological Sciences, and I run a website, called the Cichlid Research Home Page . I also write for many popular aquarist magazines, and I was editor of Cichlid News magazine for several years. I am a scientist and I spend my time teaching fish biology, ecology, behavior and evolution and doing research on the reproductive biology of fishes, particularly cichlids. I do research in the laboratory and in Costa Rica, Nicaragua and Mexico. My main interest is understanding the evolution of parental care in fishes. I am interested in encouraging greater public awareness, understanding and participation in science.
