I recently ordered and received a 6 inch Red Sea Sohal Tang from Absolutely Fish. so far, he has been a great addition to my 220 which has a Blue face, Queen, Scribbled,Flame, and Flagfin angels, Blue Throat and Niger triggers and e Heniochous butterflies... The Sohal so far has been a model citizen and a joy to watch..... Has anyone one had one that can give advice. I have read that their diet requires a significat amount of green food to avoid lateral line and hole disease...Appreciate it.....
