No I'm not sharing they all have seperate tanks. They are close enough that they can see each other and my male betta is always flaring when the goldfish gets to the nearest side to his tank. Depot, the goldfish, gets tap water and a full tank change once every two weeks whereas the betta get a half change each week and spring water. If I had a ten gallon or bigger I'd maybe put them together. I also don't want the goldfish picking up any disease from the walmart fish either.
