I had every intention of purchasing 2 dwarf gouramis today. Then the aquarium salt issue arose. I am trying to be a responsible fishkeeper. Some people/websites say you must add salt. Some say never add salt (unless for ich?) I don't understand. I 'm sure that you shouldn't take a fish from a 'salt dosed tank' and put it into a non 'dosed' tank. I'm obviously not a biologist or other type of scientist. But I am still sure. So, do I need to add salt? Don't ever add salt? skip the store completely and spend money somewhere else? I am looking forward to an opinion from someone not trying to get more of my money and knows something about the subject( same tall now cycled((ammonia-0 nitrite-0 nitrate-12ish)) with some very lucky red minnows
