Reef safe

Last updated

Reef safe is a distinction used in the saltwater aquarium hobby to indicate that a fish or invertebrate is safe to add to a reef aquarium. There is no fish that is completely reef safe. Every fish that is commonly listed as reef safe are species that usually do not readily consume small fish or invertebrates. Fish listed as reef safe also do not bother fellow fish unless in some cases, for instance tangs, they do not get along with conspecifics and sometimes fish with similar color or body shape. Every fish has a personality, is different, and, in some cases, are opportunistic feeders. Tangs, which by most accounts are reef safe, may in adulthood eat some crustaceans shortly after they molt. Many larger predatory fish, for instance eels and pufferfish, will adapt very well to a reef tank and will be problem-free as long as they have sizable tank-mates and no crustaceans. Some aquarists have also had success in keeping smaller fish with predatory ones in reef tanks by adding the smaller fish at night, sometimes with newly rearranged rockwork.

Invertebrate Animals without a vertebrate column

Invertebrates are animals that neither possess nor develop a vertebral column, derived from the notochord. This includes all animals apart from the subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, and cnidarians.

Reef aquarium

A reef aquarium or reef tank is a marine aquarium that prominently displays live corals and other marine invertebrates as well as fish that play a role in maintaining the tropical coral reef environment. A reef aquarium requires appropriately intense lighting, turbulent water movement, and more stable water chemistry than fish-only marine aquaria, and careful consideration is given to which reef animals are appropriate and compatible with each other.

Eel order of fishes

An eel is any ray-finned fish belonging to the order Anguilliformes, which consists of four suborders, 20 families, 111 genera, and about 800 species. Eels undergo considerable development from the early larval stage to the eventual adult stage, and most are predators. The term “eel” originally referred to the European eel, and the name of the order means “European eel-shaped.”

Reef safe

Fish

Anthias
Basslets
Blennies
Excludes fang blennies. A few species will nip at polyps and giant clam mantles.
Cardinalfish
Chromis
Clownfish
Excludes the maroon clown which can grow very aggressive and territorial.
Damsels
Excludes larger, more aggressive Dascyllus varieties.
Dwarf angelfish
Dwarf angelfish in a reef setting has been heavily debated.
Dottybacks
They may consume small shrimp and can be highly aggressive.
Dragonets
Foxface
Foxface and rabbitfish will occasionally eat certain corals if underfed.
Gobies
Jawfish
Pipefish
They can be killed by stinging corals and anemones.
Pseudochromis
They may consume small shrimp and can be highly aggressive.
Seahorses
They can be killed by stinging corals and anemones.
Tangs
Wrasse
There are both reef safe wrasses and ones that are notorious for killing small fish and invertebrates.
Planktivorous Triggerfish
With caution.
Melichthys spp.
Xanthichthys spp.
Odonus spp.

Invertebrates

Corals (Class Anthozoa)
There are aggressive types of coral which have sweeper tentacles that can burn other corals. These may require specific placement in an aquarium.
Crabs
Specifically small hermit crabs, anemone crabs, emerald mithrax crabs, and strawberry crabs.
Fan worms (Suborder Sabellida)
Giant clams
Scallops
Sea anemones (Order Actiniaria)
Anemones, especially carpet anemones can eat fish and burn corals to death requiring specific placement for specimens in an aquarium.
Sea cucumbers
Sea fans
Sea slugs
Starfish / Sea stars
There are many starfish which are not reef safe like crown-of-thorns starfish and chocolate chip sea star.
Shrimps
Peppermint shrimps, cleaner shrimps, pistol shrimps, anemone shrimps and blood red fire shrimps are better choices since the commonly available banded coral shrimp can kill fish, and the mantis shrimp will kill and eat most animals in a tank.
Snails
Some snails are parasitic but are rarely, if ever, offered in the saltwater aquaria trade.
Sponges
Tunicates (sea squirts)

Reef unsafe

Fish

Non-dwarf Angelfish
This includes any of the larger angelfish.
Non-planktivorous Butterflyfish
Eat mainly or exclusively coral polyps
Non-planktivorous Triggerfish
This includes most triggerfish. Most triggerfish are highly aggressive carnivores that will eat many smaller fish and invertebrates in an aquarium. They also grow to be quite large.

Invertebrates

Sea apples
Currently short-lived in aquaria. They release a highly-toxic substance at death, decimating the aquarium.

The Redtoothed triggerfish is a triggerfish of the tropical Indo-Pacific area, and the sole member of its genus. Some other common names include Blue Triggerfish, Redfang Triggerfish, Redtoothed filefish, and Niger Triggerfish.

Marine aquarium

A marine aquarium is an aquarium that keeps marine plants and animals in a contained environment. Marine aquaria are further subdivided by hobbyists into fish only (FO), fish only with live rock (FOWLR), and reef aquaria. Fish only tanks often showcase large or aggressive marine fish species and generally rely on mechanical and chemical filtration. FOWLR and reef tanks use live rock, a material composed of coral skeletons harboring beneficial nitrogen waste metabolizing bacteria, as a means of more natural biological filtration.

Cherubfish species of fish

The cherubfish, or pygmy angelfish is a gentle omnivorous marine angelfish, with a metallic blue body and yellow to orange colouration in parts of the head only. It is native to the Caribbean and Gulf of Mexico, North to North Carolina. It has a maximum length of 8 cm. It is easily confused with the orangeback angelfish, but in the latter the orange stripe extends across the back.

The average life expectancy is 5–13 years, depending upon its location. These fish tend to grow to a maximum of 6 inches in length, making them a dwarf fish.

Cleaner fish tribe of fishes

Cleaner fish are fish that provide a service to other species by removing dead skin and ectoparasites. Although the animal being cleaned typically is another fish, it can also involve aquatic reptiles, mammals or octopuses. The cleaning symbiosis is an example of mutualism, an ecological interaction that benefits both parties involved. However, the cleaner fish may sometimes cheat and consume mucus or tissue, thus creating a form of parasitism. A wide variety of fish including wrasse, cichlids, catfish, pipefish, and gobies display cleaning behaviors. Similar behavior is found in other groups of animals, such as cleaner shrimps.

Coral reef fish fish which live amongst or in close relation to coral reefs

Coral reef fish are fish which live amongst or in close relation to coral reefs. Coral reefs form complex ecosystems with tremendous biodiversity. Among the myriad inhabitants, the fish stand out as colourful and interesting to watch. Hundreds of species can exist in a small area of a healthy reef, many of them hidden or well camouflaged. Reef fish have developed many ingenious specialisations adapted to survival on the reefs.

Coastal fish

Coastal fish, also called inshore fish or neritic fish, inhabit the sea between the shoreline and the edge of the continental shelf. Since the continental shelf is usually less than 200 metres deep, it follows that pelagic coastal fish are generally epipelagic fish, inhabiting the sunlit epipelagic zone. Coastal fish can be contrasted with oceanic fish or offshore fish, which inhabit the deep seas beyond the continental shelves.
