This is a new species to us and the hobby, we believe it is a variation of Gracilaria or Agardheilla, but have not been able to confirm it's identity. The species lives alongside Ulva and Gracilaria species, and has similar care requirements. It can handle bright light, but should be introduced to it over time. The plants we ship will be small, about 2 inches wide and 3 inches tall. Those are about as big as we have seen them so far, we are unsure how large they can get.
