I just wanted to know what are the easiest, hardy fish to keep in a 160litre (don't know gallons sorry) tank with slightly alkaline water (about 7.4ph)
Actually, I disagree with this statement. IME, it does you no service to start messing with the natural conditions of your home's tap water, except removing chlorine from city water. It is nothing but a headache to try and alter the ph or hardness of the water of the average fishkeeper. A stable set of conditions that are a little different from the conditions that the fish you choose prefer (within reason), or from the conditions of the tanks at the lfs, is much better than trying to monkey around with your water's natural chemistry and have constant fluctuations (as well as buying tons of corrective chemicals that aren't really neccessary.)Originally posted by thom336
always check with your dealer the conditions they keep the fish in, and match that in your home aquarium.
