Woefulrelic, I have had her 18 months now and she hit 12 inches in a year! She is now 14 inches. You are total correct regarding the diet, when young it's mainly anything they will eat but after 6 inches it need to be primarily 'crunchy' food. Manual clipping of teeth is a nightmare... I tried with my South American puffers but it is horrific for both fish and owner. So when I got my hairy puffer (who is a total killer) and then the fahaka I made sure that a diet heavy in shell on food was the order. Since then I have never had to clip their teeth. Watching her crush a whole clam for the first time is quite impressive and you respect the teeth! My fahaka and hairy puffer have come very close to taking a chunk out of me! But you learn fast with puffers lol
