While I agree with you to a point that chemistry is generally not that important - stable water is better than perfect water so I would not use any products to alter the water chemistry unless your water is at an extreme. Even then, there are natural ways to do it.
Most strange looking fish require larger tanks to 48+". You could probably keep an afican butterfly. It's not an active fish - it sits around in a big tank just the same as a small tank IME. It is certainly an odd looking fish - it's closest relative is the arowana.
