I thought only tang cichlids were freshwater that had the requirements you describe. Oh well in any case its funny how instead of correcting me and helping the op you singled out my answer. Hmmmm, wonder why guess you weren't trying to help the op like I was, it almost comes off as though your interest is only in feeling superior. That's why I used comments like as far as I know instead of definitives. Still I could be wrong, just tell me why you didn't give the op help but correct me if your only reason is to help fellow hobbyists out. How ever I'm sure you'll agree there is a greater concentration of salt in Malawi water then CA/SA water correct? So what do you call this saltier water? I checked it out all over the place even though its not as brackish as say the water that Chromis live in its still salty. So what's wrong with calling it brackish to someone when I wasn't going to pick at everything and be exact. I figured it was easier to say brackish. Also enlighten me what do you call water with a higher salt content than fresh, but not as high as say where Mono's and Chromis live? So I can properly refer to it next time.
