Since this tank is really hubby's I don't usually buy much for it, but I actually went out and bought this coral all by myself! I was on a business trip in RI about 3 hours from home and decided to check out the local fish stores to see what they had. I found this gorgeous piece of coral. It was twice the size of the one bubble coral our own LFS had and half the price. They also swore up and down if it was ever exposed to air it would immediately die! Yeah, well I guess we've all found out how reliable many of the employees at LFS are. We did accidentally pop one of the buubles when we first put it in but it either healed up or replaced itself or whatever it does because it seemed to go away after a few days.
