Hello everyone me and my family are new to betta fish keeping, we have a gold fish but wanted something different/better. My son fell in luv when he saw the bettas at the pet store so we picked up what the lady said we needed. ( 1gal tank no bigger per fish or it will stress the fish out so we got a 2.5gal, she said that we didn't need a filter but we picked one up any way, and fish food) we picked out three bettas 1 male, 2 females (scence there said to get along ok), got a divider and went home. The next day the bigger female was attacking the smaller one so we took her back to the store. Would have kept her if we had another small tank. Its been a month scence then and two days ago my husband noticed that are male was laying on the floor of the tank not really moving a few mins latter he was gone
. We changed the tank and took my son to pick out another fishy. We brought him and put him in the tank, he must be happy I think because I get home from work and he's started a bubblenest up by the filter.
I still need to get a tank heater and a thermastate considering the lady said nothing about a sertin temp being needed.
Sorry so long but if any advice would be helpful. I do plain on puting them both into a ten gallon tank once we get settled into are new home but for now would a 2.5gal be ok? And even with a filter should I still changed the water 2-3 times a week?
