Intricate relationship allows the other to flourish : Sea Anemones - AskNature
This photo of the Purple Condylactis variety sea anemone in our Based on the natural symbiotic relationships between Clownfishes and Sea. In their natural habitats, clownfish and anemones have a symbiotic relationship; both need the other to survive. Clownfish rely on anemones for. The Condy Anemone are a commonly available. and are seen as cream or white with tips that are peach, green, white, gold, purple and pink. Using a C. Gigantea anemone to host Clownfish is very risky, especially as They also have an interesting symbiotic relationship with juvenile Cardinal Fish.
Their life span however is still unknown at this point. Some anemones have been recorded to live for hundreds of years in the wild with some in captivity been reported at over These anemones will frequently split in captivity also. They will come in a range of colors from peach, green, white, gold, purple and pink.
Mostly their tentacles will be a white or cream color with tips in one of the above colors or even just a small dot found on the end of each of its tentacles. Tentacles will be spaced out and quite a bit thicker at the base, then tapering towards the tip.
They will have a wide sticky foot at their base that they use to adhere to different surfaces and use to move around. This is done by contracting the circular muscles found in the foot and pushing itself forward or can even crawl on their sides. This sticky foot is generally various shades of yellow, bluish gray or a brick-red color.
An oral disc is located at the top of the column with a mouth in the center, and tentacles around the outer margin of this disc. A wide gaping mouth is a sure sign of ill health.
Condy Anemone - Who Gives A Fish
Folding up into a ball is done during times of threat or if water quality is not to their liking. Your tank should be at least 4 months old with stable conditions before adding one of these anemones. The Western Atlantic is home to much live rock and sand environments, so these anemones need some live rock or other solid structures for them to adhere to and move over.
Any substrate is acceptable with moderate water flows being ideal, as well as some moderately strong lighting. These Condy Anemones are extremely mobile and are predatory in nature. You must ensure that all of your pumps are covered well with guards to stop the anemones wandering in and being minced.
Foam filters should be places over any power heads intakes as well. Strong, direct light Temperature: The clownfish, while being provided with food, cleans away fish and algae leftovers from the anemone. In addition, the sea anemones are given better water circulation because the clownfish fan their fins while swimming about. Clownfish live at the bottom of the sea in sheltered reefs or in shallow lagoons, usually in pairs.
Clownfish have a special relationship with the anemone and are very important to them. They are a large help to the anemone as they clean the anemone by eating the algae and other food leftovers on them.
They also protect the sea anemones by chasing away polyp-eating fish, such as the butterfly fish. The map below shows where in the world clownfish can be found.
They live in the warmer waters of the Pacific Ocean and Indian Ocean. There are no clownfish in the Caribbean. What is the Life Cycle of the Clownfish? The spawning season of the clownfish, a time when they breed, is year round in tropical waters.
Males attract the females by courting. Courting behaviours include chasing, biting and extending fins. Clownfish lay their eggs in batches on coral, rock or next to the sea anemone that they call home.
The male clownfish will build a nest on the rock or coral near the anemone in order to be provided with protection from predators. Breeding starts by the male chasing the female to the nest where the eggs are released.
One hundred to one thousand eggs are laid. The male clownfish guards and protects the eggs until they hatch. Belonging to anthozoan Order Actiniaria hence the term "actinian"they are members of three different families. The Actiniidae, of which Entacmaea and Macrodactyla are members, is the largest family of sea anemones, and that to which most common, temperate, shore species belong.
The exclusively tropical Stichodactylidae, with genera Heteractis and Stichodactyla, is the main host family. Also tropical, Thalassianthidae contains three genera, including Cryptodendrum. Unlike the fish, in which all members and only members of damselfish subfamily Amphiprioninae are symbiotic, most members of families Actiniidae and Thalassianthidae do not participate in symbioses with fishes, and there are also some non-symbiotic stichodactylids.
They deal with features such as nature of the animal's muscles, size and distribution of nematocysts, and arrangement of tentacles in relation to internal anatomy.
Such characters, which are retained in preserved specimens, require dissection and histological examination to study. They are used partly because most species from the tropics especially prior to the 20th century and from deep seas until the recent advent of submersibles were originally known only from preserved specimens.
We believe actinians can be identified in the field, based on appearance and habitat, although some experts consider nematocyst analysis essential. A sea anemone is an extremely simple animal. It may be thought of as a cylinder that is closed at both ends. The lower, or pedal, end may be pointed for digging into soft sediments. In anemones of most families, like the host actinians, it is adapted as a pedal disc, which attaches firmly to a solid object like a coral branch or rock often buried in sediment.
In the center of the oral disc, at the opposite, unattached end, is the mouth. Hollow tentacles, arising from the oral disc, surround it. They may be few or many, and arrayed in radial rows or in circlets. Their form is highly diverse -- short or long, thin or thick, pointed or blunt, globular or tree-like.
Tentacle number, form, and arrangement are very important in distinguishing genera and species. The cylindrical column body of anthozoans is not completely hollow, the name Coelenterata notwithstanding. In sea anemones, vertical partitions mesenteries extend from the column wall across the central space part or all of the way to the throat actinopharynx.
Viewed in cross-section, the column therefore resembles a wheel with spokes. In animals with few tentacles, much of the oral disc, the mouth, and sometimes even the upper end of the throat, into which the mouth opens, are visible. The disc can be radially or circularly patterned; the mouth, which can be circular or elongate, may be elevated on a conical projection and may differ in colour from the oral disc. In most species of host actinian, the oral disc is much broader than the column.
The column, which may be patterned commonly splotches of colour or longitudinal stripescan also bear specialized structures along part or all of its length. For example, some tropical anemones but none that hosts clownfishes have branched projections from the lower column. Most host actinians have, in the upper part, longitudinal rows of small warts verrucae; singular is verruca to which particles of gravel may adhere; commonly these are pigmented differently from the rest of the column.
Sea anemone colour pattern can be important for field identification, but colour itself, being highly variable in most actinians, is of little diagnostic value. Symbiotic algae may affect anemone as well as coral colour, either by imparting their own golden brown colour, or by stimulating the animal to produce a pigment that protects the algae against excessive sunlight. Therefore, anemones often blend in with corals and with sand, explaining how such large animals may be so difficult to detect in nature.
Presence or absence of verrucae is a character defining genera. Thus, all species in a particular genus do e. Stichodactyla or do not e. Arrangement of tentacles is also important in defining genera. There may be one tentacle per space between mesenteries so that number of tentacles equals number of mesenteries attaching to the oral disc or there may be more than one tentacle between each two mesenteries.
Members of the family Actiniidae have one tentacle per space. Anemones of families Stichodactylidae and Thalassianthidae can have so many tentacles because up to several, radially arrayed rows of tentacles arise from alternate spaces the endocoelswhereas only one tentacle arises from the other spaces exocoels.
The single tentacle is positioned at the very edge of the oral disc margin. This arrangement may be obvious when the animals are well extended. Keys and descriptions may not work well with captive animals. As explained in chapter 6, aquarium-kept anemones can lose their colour after a remarkably short time, probably because their algae do not thrive under artificial conditions, and tentacle shape may also change. Fish symbionts should not be used to identify anemones in captivity, as they can be in nature, because many fishes can acclimate to most host anemones.
Tentacles of the two forms usually different colours: Details Oral disc to mm diameter, flat when expanded, but commonly undulating. Entirely covered with tentacles except immediately around mouth, which can be fuchsia, yellow, green, white. Moreover, tentacle stalk and tips may differ in colour. Therefore, may be extremely colourful animal. Similar species Specimens of Stichodactyla are superficially similar, with many, short tentacles.
However, the two distinct types of tentacles arrayed in separate fields is a feature unique to C. Tentacles of other species may adhere, and pull off the anemone; those of C. Bulb seems to be related to presence of fish, and can disappear; tentacle lacking a bulb has white ring where equator would form.
Tentacles without bulbs are blunt-ended.
