Pimafix is an acceptable "natural" antifungal treatment. Melafix is for bacterial infections. Kanamycin, erythromycin or metronidazole are good broad spectrum antibiotics. Fungus Cure (by API) is an excellent antifungal. You can find these medications in the aquarium section of most pet stores or even online. Follow label directions carefully and remove the carbon filter insert during treatment if indicated. The cornerstone of any treatment is to first maintain pristine water quality and stable chemistry.

Check the water chemistry and quality first. Poor quality can predispose him to infection. Use a home test kit or submit a water sample for testing. Your local Petco may do this for free or for a small fee. If ammonia and/or nitrite levels are elevated, perform partial water changes until both read 0 ppm and nitrates are 20 ppm or less. Use only conditioned water that is temperature matched to prevent further stress or shock. Providing pristine water quality is the foundation for treatment and healing. Check the water temperature since low temps can affect appetite and activity in fish. If the water is too warm, it can also affect activity since warm water does not hold as much oxygen as cooler waters. Fast the fish for 2-3 days then feed tiny bits of cooked and shelled green peas. This will aid in defecation if there is constipation. Plain aquarium salt (not table salt or Epsom salt) can be used for most fish as a general tonic to reduce stress, improve gill function, treat minor in

Thanks for reaching out about Fish. Test and correct water quality for pH, ammonia, nitrites and nitrates. If all fish are affected, water quality problems the most likely. Alteration can lead to increased mucous production from the skin (white stuff), but fungal dermatitis or parasites are also possible. A veterinary visit is recommended if the water quality if appropriate, to assess and provide a diagnostic/treatment plan. Good luck.

Food, genetics and stress can all affect colors. There are color enhancing diets that you can buy. Maintaining pristine water quality and stable chemistry will limit stress. If the fish has muted colors due to genetics, there is nothing to be done. As far as being "shy", this can be due to anything that is stressful or potential illness or injury. This would require and exam to diagnose.

It's not really recommended to keep fish in bowls with no filtration. And 2.5 gallons isn't really big enough for much. A Beta fish may possibly do ok in it if you can maintain it. But I would recommend more doing plants and a few snails or ghost shrimp type of animals in a bowl that size.
