The Deep Dive on Reef Aquarium Lighting, Part 1: Zooxanthellae, Color Temperature, and Light Intensity
LEDs continue to gain a loyal following as a capable reef lighting technologyLighting is important because it directly affects how we visually enjoy the hobby and, more importantly, the vast majority of the corals in our tanks are photosynthetic. In this two-part article, we will first cover some of the basics of the light itself and then discuss the various lighting technologies people use to light their reefs. Coral and zooxanthellaeCoral as we know it is a symbiotic relationship between the coral animal and dinoflagellates called zooxanthellae. Zooxanthellae live in the tissue of the coral and are like algae in that they contain chlorophyll for photosynthesis. The byproducts of photosynthesis are things like simple sugars that the coral hosts can use as an energy source. It is for this reason that coral are often described to the layperson as having traits of both plants and animals. The color of zooxanthellae is varying degrees of brown. However, there are over 80 known varieties of zooxanthellaeKeeping The Rainbow Belly Pipefish

Microphis deocata, also known as Indian Royal Green Pipefish or Rainbow Belly Pipefish, are one of very few completely freshwater pipefish species on the planet. They are a small brownish green pipefish that grow to a maximum of 6.5″. What makes this species truly unique is the brightly colored sail the females of the species use for courtship. Microphis deocata are found in the Brahmaputra River that runs between India and Bangladesh. They are a threatened species as a result of seasonal flooding within these two countries and are not commonly available commercially in the aquarium trade. There is very little information available at all on this species and so I am offering my experience with thisReef Threads Podcast #287
