White fungus growing on my betta fish?

Hello, We have noticed a white bump growing on our betta fish on the top of his back near his fins

My betta fish seemed to have fungus growing on his fins and he was very inactive -- staying at the bottom of the tank; not eating very often. I bought a powder for his fungus growth and after a few days the white patches on his scales went away, so I believe that the fungus powder had worked. But my fish's behavior hasn't changed. He is no longer eating at all and he just looks like he is struggling to live. It is painful to see him in such bad shape, but I don't know what to do. Should I try a different treatment? Or should I just let him fight on to the end?

Fungus on bettas it usually fluffy,white cottony patches. If you frog has fungus then your fish will get it. Usually it will grow fast especially with wormer water. So you need to be ready and have medications in case it is fungus. Also with betta you can treat them with aquarium salt. So if you can have hospital tank for your betta since only bettas most tolerant to salt in higher dosage.

How has your betta fish's appearance changed? When I bought him in January I noticed a small oddity about his scales on the side of his body near his tail. At the time I thought maybe he had gotten into a fight with another fish when he was in the breeding facility and it was a scar. He was a Wal-Mart fish after all and I'm sure they don't use the best suppliers. Everything seemed fine, other than an occasional very small swelling in the area. As recently as a few days ago, a white "lump" for lack of a better word, has started breaking through his scales and is growing very slowly. He has also developed fin rot that has accelerated quickly.How has your Betta fish's appearance changed? **I've included a picture* strange lumps developed on her tail and dorsal fins. They seem to be getting larger. They were the same color as her scales at first, but as they grow, they get whiter.There are drugs to white spots can be found in the LFS but you should remember that the stronger the individual drugs as stress. Malachite green is not recommended for use for catfish as catfish, Betta fish chạch and the other fish such as tetras. Treatment of 4 waves, each wave lasting 3-4 days, about 50% water changes before each treatment. Continue treatment for two weeks to ensure that all parasites are killed off. Remember, only drug effect on larvae of the parasite or about the first 3 days of their growth cycle. (Note: in Vietnam, commonly used treatment for white spots is methylene blue. Brands available in tablets and liquid circulation in the market. Should read carefully the rate of medication instructions before use because the concentration each type may vary). This group of fish can easily be mixed together without any aggression or predation problems. This group of fish includes some of the hardiest and most easily kept fish, allowing you to keep groups of them in a smaller space than larger growing fish. Examples of these fish include: livebearers (mollies, platys, and guppies), small growing barbs, most tetras (schooling), rasboras (schooling), danios (schooling), white cloud mountain minnows (schooling), killifish, small growing catfish species such as corydoras (schooling) or hoplosternum catfish, algae eaters such as bristle nosed plecostomus or otocinclus catfish (avoid the common plecostomus as they grow very large and do not eat much algae once mature), certain dwarf cichlids such dwarf gouramis, and of course bettas.
