I was blessed today with a couple of new frags for my tank, a leather hand (about 2" across), a blue and white candy cane (12 heads) and a todd's torch (2 heads). As the guy was cutting the torch for me, one of the 2 heads cracked. I have it in my tank right now in a protected position basically holding the cracked head together. The sweepers are out and it was quite pleased when I pumped a couple of ml of brine shrimp into the middle of it. Need I be concerned about the cracked head? Will it heel on it's own or should I pull it out and put a bit of super glue on it?
