Easy Soft Live Corals for Reef Aquariums

Common names include: finger leather, cauliflower, and colt coral

Cladiella are hardy corals that adapt well to aquarium life. They thrive in moderate lighting and water movement conditions. Because they grow and reproduce so well, they may overgrow other sessile (stationary) reef animals in the aquarium.

Common names include: mushroom coral, mushroom and disc anemones

Most varieties of discosoma require little light and may, in fact, do poorly under bright lights. These corals obtain much of their energy from active feeding, including trapping and consuming small fish. In an aquarium, they will also consume uneaten food and detritus that is deposited on them by water currents or sand sifting fish.

Common names include: star polyps, green star polyps, daisy polyps

Pachyclavularia are sensitive to iodine additions (in the form of Lugol's solution) and aluminum oxide (found in many phosphate-removing sponges). These corals are tolerant of both low-level and bright lighting and are capable of reproducing and spreading quite rapidly in an aquarium.

Common names include: sea mat and button polyps

Palythoa do well in areas of rapid water movement. These corals are light-tolerant but will grow quite rapidly under bright lighting. Their placement in an aquarium should be considered carefully, as they will overgrow most other corals.

Common names include: sea mat and​ button polyps

Protopalythoa corals are tolerant of many lighting conditions but prefer bright light, which may produce fluorescent highlights. Some of these corals are active feeders, feeding on large food items, rapidly engulfing and consuming them.

Common names include: toadstool, toadstool mushroom, leather, mushroom leather, trough coral

Sarcophyton are hardy corals that prefer low to moderate current, which helps to keep its surface free of parasites and other predators. They adapt well to many lighting levels and feed by taking nutrients directly into their cells from the sea water. These corals do well in a reef tank with less-than-perfect water conditions and may well suffer in water that has had a majority of the dissolved organic compounds (DOCs) removed through skimming.

Common names include: zoanthid, sea mat, and button polyps

Zoanthus corals greatly prefer bright light, as they depend on their zooxanthellae for nutrition. They also feed on bacteria, algae, and DOCs.

Common names include: finger and finger leather coral, colt coral

Alcyonium are hardy corals that do well in aquariums but should be provided with bright lighting and good water movement. These corals contain zooxanthellate but do need to be fed. They may require phytoplankton for best growth, while consumption of zooplankton is reported to be rare. These coral may overgrow other sessile animals.
