That fish looks very similar to my Max in both color and shape, but it doesn't appear to have lost it's color in clear water. I find that very interesting. I wonder if the water needed to simply be soft instead of black. I didn't try that.
yeah I don't know if his water was soft or hard. This guy was 9-10" and died a week after @JLSEF9 acquired it (banged its head against the wall hard).
