wondering what an ok size would be for a hospital tank. i have danios, platies and will be getting a betta after new years. need it to be small as i dont have a lot of room. what is the smallest size tank i can use for these fish safely?


/www.drsfostersmith.com/product/prod_display.cfm?pcatid=21425, the smallest one would be fine for a 5 gallon tank. The only other thing is you would need to buy eithor a powerhead or a pump for it, in a 5 gallon I would go with a pump. But you would have to buy that anyway even if you made it yourself.
