Im having a 4G (UK) fish tank for a male betta and a couple of shrimp if he agrees to them etc. Im getting a heater at the end of the week or tomorrow depends how much money i ahve on hand etc. but not having a filter. I know i have to water change it very 3-4 days without having a filter and this Im fine with. how long would I have to wait till I could put a betta and couple of shrimp in? i have put water control in (Because its tap water)
