Both of these were really tough. The Naoko was my first big loss. It was a dream fish and though I only had it a couple of weeks it had shown so much personality. Unfortunately it UNWD and watching it slowly die until finally I had to euthanize was awful.
The regal was another dream fish and I still consider them perhaps the most beautiful fish in the hobby. Mine was a tiny CB one that someone had given up. It had some HLLE when I got it but I managed to get it back and healthy and beautiful. Then I introduced an unquarintined tang. The regal was my last fish to die of velvet and perhaps the closest I’ve come to quitting the hobby.
