I am fortunate to have a well above average store just ten minutes drive from my house to purchase my corals. They are always attached to a decent piece of rock and from there its just a matter of finding a sturdy local amongst the rock in my tank. The only coral I had to glue to any thing was the mint green candy cane frag which I used super glue gel for.
The store is also vary reasonably price or I don't think I would have been able to afford all the additions I have made in this short a period of time. The latest addition was the green hammer at only 60 bucks. My Xenia was the size of my fist at purchase and was only 20 bucks. Mint green candy cane frag 20 bucks. That large group of sand polyps just 30 bucks, the acen frag just 20, the devils hand was 38, sand polyps 20 small group of green polyps 20 and the green star polyps with the few cinnamons ran me 48 but that rock is at least a foot long and completely coved in polyps.
The weird thing is the same store charges 10.99 a pound for premium LR. Go figure.
