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.

It should be okay to use these tanks as long as they have proper filtration, lighting...etc. Round bowls typically don't have filtration, lighting...etc and that's what will adversely affect the water quality. I hope this helps.

To a degree yes. I recommend to have at least 6 hours of light a day. Do watch for any lesions on the skin. Ick and fungal infections can make fish lethargic or can be opportunistic infections when fish are stressed. Also make sure you are feeding a gold fish specific diet. You will also need a larger tank as they grow but right now they may be ok. In general, 1inch of fish needs 1 gallon of water. Gold fish are pretty 'dirty' as fish go so make sure you have a good filtration system. I hope this helps.
