I’ll be sad to see it go honestly. It’s been with me 3 years. Last 2 years in my 180 with about 8 or 9 other tangs and haven’t had any problems other than some aggression. As the fish grow Iv been taking them out 1by1. I can see the aggression slowly building so at that point it’s time for a bigger home or less stalked tank in my mind. I will be down to 5 tangs once I find a home for this guy.
I definitely took some precautions. Ran all the fish through quarantine initially and truly feed the crap out of them several times a day with all kinds of foods. My process isn’t perfect though as I have since added corals and inverts into the system that weren’t properly quarantined. Reef tanks are hard but I sure do love the hobby! Tank pic added.
