What to do????

Like i've said i have constantly been fighting a type of fish fungus so i took my last rammer out of my tank and put him into my old betta boul hopingthe fungus might clear up and it did do i bough 5 gold fish hoping that if the fungus came back it would the the 5 30 cent fish instead of my 5 dollar rammer. the fungus is now gone and my gold fish are fine but in my betta tank the fungus has grown there!!!! Dose that mean my rammer is the creater of this fish fungus???

Well, it could be the fish or it could be the water.. is the water in the betta bowl from the tank? or is it tap or RO? and also im assuming this is saltwater is it?

IN the betta bowl is just tap water that I put conditioner in. I think it might be my fish but he dose not seem to have any fungus on him...

A small Betta bowl has has such a small volume of water that it can turn bad very quickly. If there is even a little bit of uneaten food or other waste, it will pollute the water and make the fish sick. Goldfish cope with dirty water much better than other aquarium fish, so your large aquarium could still have a problem. Regular, partial water changes usually fix most water problems, and it's a good idea to test the water, at least for ammonia, before replacing the goldfish with a more exotic species.
