Fish/is my fish sick


ive had my betta for about a month and recently noticed that he is growing a white/green algae from his head and all over his scales and what should i do

I would do a waterchange and then try a medicated bath or medical solution. There should be a wide variety of antibiotics for this at your local fish store. I recommend going and seeing what they recommend based on the products the have in stock.

I can answer questions relating to the scientific aspect of the hobby (fish ecology, biology, genetics, etc. ), aquacultural and breeding aspects, and have experience with nearly all "brackish" fish in the trade. I also have lots of experience breeding fish, like angelfish, tetras, cichlids, and various livebearers. I also have lots of experience with many freshwater fish, especially "monster" fish, like stingrays, arowana and Saratoga, cichlids, catfish, etc. Please ask questions about anything except for true saltwater (reef) tanks.


Too much to fully list, but I will never have never enough to satisfy myself.

Student, but I've been involved in many projects involving aquaculture and fish biology. I'm currently helping design a massive stream improvement project on the St. Vrain river. I am studying fisheries ecology, techniques, hatcheries, and management practices for north american freshwater systems.
