Pete those hystrix are beauties, fat and healthy!!....I remember we corresponded around the same time you bought them from TUIC.....I only got a male due to size constraints, and he is just as nice as yours...he was 6-inches when I got him in early December and is now 10-inch disc......very fat and healthy....my only regret is not getting a female at the same time.....I am hoping some show up soon!! Again, your fish are great!
