Acropora Frag

A frag, meaning a small cut fragment taken from a larger parent colony, giving you a head start on a coral that would otherwise take considerably longer to reach the same size from scratch. This is genuinely demanding SPS territory — Acropora wants strong, stable lighting, brisk flow, and calcium, alkalinity, and magnesium held in a tight, consistent range, since it's far less tolerant of swings than the large polyp corals most people start with. Get the parameters right and growth can be fast enough to notice week over week; get them wrong and it's usually one of the first corals in a tank to show visible stress through tissue recession.
