Care Level

We have included a general guideline in our Quick Stats of the level of care that the different corals and invertebrates require. This is provided to give you a basis of the hardiness of the species, which you can then match to your level of experience. 

Easy 

Although not indestructible, the species in this category have proven to be not too demanding in the care that they require. Most of these corals and invertebrates do not have special feeding requirements and can tolerate less than perfect water conditions. 

Moderate
The corals and invertebrates in this category demand a bit more attention than those that are considered "Easy" to care for. Some of these corals may have special feeding, lighting, or water movement requirements and may require water conditions closer to those found in nature. 

Difficult
Species that fall into this category demand a higher level of both attention and water quality. Many of these corals and invertebrates have special feeding, water quality, movement and lighting requirements. They should only be added to a reef aquarium that is well established. Many reef aquariums do not become fully established for many months, and sometimes up to a year. These "Difficult" species should be among the last additions to your collection. 

Expert Only
Organisms in the "Expert Only" category are very difficult to maintain in captivity in the long term. The requirements of many of these corals and invertebrates are specialized, and may need to be kept in a species-specific aquarium. These species are best kept by the most advanced hobbyists and research institutions. A well-established reef aquarium is a must for these species.
