Jazzman, I don't believe anyone is intentionally targeting the Quoyi with meaty foods, as most everyone on here has stated they all are eating nori, spirulina flakes and wafers and formula two pellets. I will give you that most people know little or nothing about what their particular fishes diet needs are. With that said almost everyone who has commented on this thread owns a Quoyi and have been in this hobby for many years and may have read a few books here and there. If you don't have a tank with a lot of liverock for grazing and teeth dulling I'm sure there could be health issues, then again there are long term health issues for a banded catshark in a 55g that was purchased as a egg for 40$
