Your tap water is good for normal keeping, you don't need to do anything more unless you're looking to breed them. I have only had A. iniridae once and they required a pH lower than 5 for successful breeding. I had soft water from the tap (<2 dGH) so I just filtered the water over peat to get the desired pH. Your water should be soft enough so that you don't need RO or deionized water. /Fredrik Frode Johansen wrote: > > Hi. > This weekend I bought 10 young Apistogramma iniridae. > Can anyone tell me what condition they require?
