The diminutive wrasses of the Wetmorella genus are charming but make excellent targets for bullies. If bullies start to harass them, they’ll retreat to rockwork and eventually die of starvation or disease. These fish are best kept in small to medium tanks with peaceful tankmates. They’ll prefer a refugium for refuge, and will eat copepods and small crustaceans.
Wetmorella wrasses are very peaceful and peacefully wrasses with a quiet disposition. They need heavy rockwork for their habitats, and will occasionally come out of caves to search for morsels. Wetmorella wrasses are fairly slow moving, and they swim hoveringly. Their reserved behavior makes them ideal candidates for aquariums, but they need a certain amount of space.
Wetmorella wrasses are quite shy and hide away in holes and crevices. They are found in habitats with rich sessile invertebrate growth. In some cases, they have even been found on rubble slopes. At night, these wrasses secrete themselves and rest in crevices. They grow to a maximum length of 5.0 to 6.5 cm.
They live in small groups, often with only one male. They are nocturnal, and can easily hide in rocks when threatened. They are quite peaceful with other species, but will bury themselves under the sand when threatened or in need. When you’re keeping a wrasse, be prepared for a bit of territoriality, especially if your tank mate is a different species.
The Wetmorella possum wresses are one of the most common species of wrasses. They are relatively easy to keep, but they can be aggressive with small fish. Be careful with feeding them – they like live foods but are quite aggressive when threatened or in need of a rest. You should make sure that you have enough live food for them to burrow in sand.
Wetmorella possum wresses are very easy to care for and have very colorful, beautiful, and unique personalities. They are native to the Philippines and Indonesia. Their appearance is similar to that of candy basslet, a popular high-dollar fish in the Atlantic. They spend most of their time scavenging for benthic invertebrates in reef crevices. They need at least a fifteen gallon aquarium.
The tiny Tanaka’s Possum Wrasse is a reef-dwelling fish native to the Philippines and Indonesia. It spends most of its time close to rocky crevices, where it hunts for small benthic invertebrates. Its ocelli are large, located on its dorsal fin and anal fin. The tail has two lines running from the end of the anal fin to the tip of the tail. Its wrasses measure only two to three inches in length.
Tanaka’s possum wreasses are not aggressive towards other species and are not particularly difficult to keep. The species is best kept in groups of similar-sized fish. Be sure to provide plenty of hiding places and visual barriers to keep them safe. Generally, wrasses live in groups of around three or four and are best kept in a tank that is about four cubic feet in size.
The Tanaka’s pygmy wrasse is low-maintenance, and not demanding. They are good tankmates for peaceful fish. They do not prefer aggressive tank mates, so they are best kept with peaceful to semi-aggressive tankmates. Tanaka’s possum wrasses do not bother corals or invertebrates.
Superlative reef wrasses
Small and secretive, the three members of the genus Wetmorella are a relatively recent addition to the aquarium hobby. They live in the interstices and caves of coral reefs, where they feed on natural invertebrate fodder. Despite their appearance, they are not a threat to ornamental invertebrates or other aquatic invertebrates.
These wrasses are extremely beneficial to possums as they clean the fish that they feed on, removing parasites and scar tissue. They often sleep on the reef bed during the day, excreting mucus cocoons in the darkness to keep warm. At night, you may see them floating in the dark and in a trance-like state. When the lights come on, the remnants of their mucus cocoons may be sloughed off.
There are other fish that are excellent choices for possum aquariums. While possum wrasses are generally shy and will avoid tank bullies, they may be the target of aggressive, larger fish. However, a wide variety of fish will ignore them. In a 90-gallon community tank with redstriped pacific hogfish, pinkstreaked wrasse, and several fairy wrasses, possum wrasses did not cause aggression toward any of the other fish.
There are 75 different species of Halichoeres in the hobby. While the vast majority of them are reef safe, some are not. They spend their days in the sand, regulating the pod population. This can lead to starvation in pod-dependent fish, so it is necessary to carefully select your pets to avoid these predators. The fact that they are such a helpful mutualist suggests that these creatures are not evolutionists.
Wrasses, or halichoeres, are a group of fish in the family Labridae. They can be found in the Atlantic, Indian and Pacific oceans. Their common name refers to their large size and colorful stripes. In the wild, they are found in a variety of habitats and are commonly caught as game fish. Here are some interesting facts about halichoeres:
The genus Halichoeres is widely distributed and has high levels of biodiversity in the Indo-Pacific and New World tropics. The genus’ diversity is particularly striking in the latter part of the world’s oceans, including the Indo-Pacific and Red seas. We tested Halichoeres in these areas for their evolutionary origins and discovered that they are polyphyletic, with distinct New World Ocean and Indo-Pacific Ocean components. The two lineages separated at around 21.2-18.1 mya, and the two halves subsequently diverged, leaving the genus in the New World tropics. This divergence suggests that Halichoeres originated in the ancient Tethys Sea.
There are many species of Halichoeres, but chrysus, biocellatus, timorensis, trispilus, and claudia are the safest ones. The species range in size from three to twelve centimeters, so keep an eye out for them in the aquarium. They can be peaceful and very easy to care for. Listed below are some species of Halichoeres wrasses:
Among the wrasse family, checkerboard wrasse is the largest. They are found in the Indian Ocean, Pacific Ocean, and the Indian sub-sea. They don’t venture into brackish environments, so they typically inhabit shallow habitats. Some species reach 230 centimeters (7 feet) in length and are as small as six inches. Their protractile mouths and teeth are designed for crushing prey.
The possum wrasse is a shy and reticent species. They can be a target for tank bullies, so keep them away from those fish. But many fish simply ignore them. In my 90 gallon community tank, I kept possum wrasse along with redstriped pacific hogfish, whitebarred wrasse, pinkstreaked wrasse, and several fairy squigglers. I was pleasantly surprised that the possum wrasses did not evoke any aggressive behavior in the other fish in the tank, and they were not spooked by other species.
Wrasses are a diverse group of fish that can reach enormous sizes. From the tiny pinkstreaked wrasse to the huge humphead wrasse, wrasses are present in almost every coral reef community. The possum wrasse is among the smallest of the wrasses, reaching only 6.5 cm in length, and the humphead wrasse is among the largest bony fish in the world, ranging from 2 m in length.
Halichoeres wrasses are near perfect aquarium fish. Their size is small enough to accommodate any medium aquarium. In the wild, they grow to between 25 and 18cm. But in captivity, they are much smaller. Most of them are 12-15cm, and the only possum wrasse found in the Red and Arabian Seas.
The Greenbird wrasse is a male species. They feed on brittle stars, mollusks, and small fishes. In the aquarium, they are considered safe because of their small size. They are a comparatively small fish, but they are not aggressive. The male is green and has a protruding beak. It is known as a Wyoming White Clownfish.
