Beautiful fish! Keep an eye on the Clown trigger; they can play nice for years, then go on a rampage. They can often have a fondness for lions fins. Not trying to be negative, I think you'll probably be ok. BTW, I think your tusk is a great choice for your tank, it takes them a while, sometimes, to spend a lot of time "out front", but they usually do.. Mine eats from my fingers and spits water out the feeding space. Those blue teeth really freak out little kids, its great!
