Coral providers often offer "Beginners Packages", an assortment of coral suitable for the early stages of a tanks maturity due to their durability. There are several species of coral that are capable of thriving in lower light conditions, some that have adapted to survive higher nutrient levels due to natural environmental factors, while others are so pervasive and low maintenance they are deemed durable simply due to limited needs to flourish.

Invertebrates account for a vast population of ocean life. Simply speaking an invertebrate is an animal that lacks a spinal cord, many like their terrestrial ecological equivalents insects possess a durable exoskeleton or shell to protect themselves from predators. Other invertebrates have developed more elaborate forms of camouflage or in some cases becoming noxious to ingestion or outright deterring predators with elaborate warning colors.

Lighting is one of the most critical—and often expensive—decisions when setting up a reef tank. The options can be overwhelming, but understanding the basics of each lighting type will help you make the best choice for your setup. Here's a breakdown of the three main categories: High-Intensity Discharge (HID), Fluorescent (T5HO), and LED, plus a look at hybrid systems that combine them.
