now, to tell you, i've kept Bettas for almost a year. at first i had no clue, and several died, then i kept a nice quartet safe for so long i was amazed.
then they all got a horrible fungus, and one lived. it kept recurring, over and over, and stopped finally. this was Flashy, the Betta who roomed in the 10g with three Goldfish.
well, Flashy got his fungus back AGAIN after a month and a half clean. he gets touchy when he's sick, and beat Speckle up so bad he floated limply, and bit Bug's eye (telescope Goldie ><") and popped it, leaving Bruiser who seemed to have died of grief (i found him lying in his corner, not a mark on him) then Flashy died.
i nuked the tank, and bought more fish. the Danios, Cories, and a new Betta. for one week i've had them, and it's the SAME THING as before. X-Ray caught the fungus, and he died. NOTHING else is fungus-y.
i'm so sad, he was such a prettyboy and so spunky. one week, and he's dead.
i'm the bane of all Bettas. i give up

for one, goldfish prefer colder water and bettas prefer warmer water. their dietary requirements are different as well, goldfish food is not betta food. most importantly, goldfish are heavy polluters of water and bettas are sensitive to that and require their water be kept clean, fungus can be triggered by poor water conditions by the way.
I beg to differ.
/b> i seem to have skipped a post. My Fallen Angel, i've been keeping this one tank for over a year (recycled for awhile with Goldies after my heater poofed on me) and just recently restocked. otherwise, i've helped my dad care for tanks for over 12 years. two years after i was born i wanted to feed the fishies. my dad has kept fish since he was 17, when he first bought the 50 (it's been cleaned and resealed numerous times) i know what i am doing, even if it doesn't follow new methods (1" of fish per gallon? pfft, what about aggressors and fat fish?)
That could very well be your problem
