Feeding Coelenterates
By filtering the water, the Coelenterates trap small suspended particles, particularly the crustacean zooplankton. Collecting, keeping, and distributing plankton is not a task to be taken lightly, and it is best to look for other solutions. However, it must be made clear that commercial foods on the market provide little more than a stopgap. It is possible to use rotifers or freshly hatched brine shrimp nauplii, normally used as the main food for fish, but not everybody breeds these animals....
Malayan snails
They breathe through their branchiae and can retreat into their tapered shell, which closes with an operculum. They relish the tiny algae which encrust the decor if they are well fed, they proliferate quickly. They are considered less effective than the planorbis, but as they bury themselves, they contribute to the equilibrium of the aquarium by turning over and aerating the bed. If you want to get rid of them, introduce a fish from the Tetradon genus, which will appreciate these mollusks....
Most Popular Plants
They could also be called the classics, as they have given great pleasure to both veteran and novice aquarists for generations. Some are of particularly interest to beginners, as they are not only easy to cultivate but also inexpensive. They are mainly stemmed plants which provide cuttings without any difficulty and grow rapidly provided they are given the appropriate level of light. Some are species that adapt to different types of water, others are more suited to a regional aquarium. The...
Marine Fish
There are almost 20,000 species of marine fish in the world, but only a small minority is of any interest to the aquarist. Of these, most come from the Pacific and Indian oceans, although a few are native to Australia and the tropical Atlantic ocean. Marine fish are usually collected in their natural environment and rarely reproduce in captivity. They find it more difficult to acclimatize than freshwaterfish, particularly as regards feeding some refuse to eat artificial food, and others have...
Turbidity
The turbidity of water refers to the presence of suspended matter - either living organisms forming plankton rare in an aquarium or inert matter, such as animal or vegetable remains or particles of sediment, particularly mud. The size of this suspended matter ranges from a few thousandths of a millimeter to several millimeters. In calm, unstirred water it forms sediment at a speed in proportion to its weight. In running or turbulent water, some of the matter remains permanently suspended,...
Pterois antennata
The antenna lionfish has four dark bands on its head. A close relative, P. sphex, has less intense coloring. The latter is hard to find in Europe, but is frequently imported into the United States. Size 20 cm. Consult a doctor immediately. The very intense pain increases for 20 minutes, reaches a peak, and gradually subsides over a period of 4-24 hours. Bleed the wound and immerse it in the hottest water possible to par 11 the action of the Obviously, the best ic to avoid getting sti take care...
Mollusks
ertain species of mollusks can be kept with fish, and sometimes with oth invertebrates, so they are popular among hobbyists. The species found in the aquarium trade are mainly carnivorous and feed on mussels or fish. There are others which graze the algae on the decor. The highly decorated shell of the Cypraea is much prized by collectors. In aquariums the porcelain-like shell is only visible when the mollusk is at rest when they are active, it is covered by the mantle the most external part of...
Nomenclature And Distribution Of Aquarium Fish
The inhabitants of our aquariums - fish, plants, or small invertebrates- all have individual names. These, however, are often the subject of unresolved disputes a single species can, in fact, have several different names Let's try and shed some light on this Xiphophorus helleri exists in a considerable number of varieties hifin, lyretail, wagtail, etc. NAMING FISHES THE CORRECT TERMINOLOGY Scientific and common names Scientific names The scientific name is the only one which is recognized...
Softened water and osmosed water
Domestic softeners produce water in which the calcareous salts are trapped by a special resin but, on the other hand, they are loaded with other substances, such as sodium. Their use is not recommended for aquariums. Osmosed water, very slightly mineralized, is obtained by using an osmoser connected to a supply of drinking water. A special membrane allows this machine to retain several substances, including calcium-based salts. The water obtained in this way is of great use to the aquarist....
Angelfish 1
Angelfish can be distinguished from butterfly fish by their protractile mouth and the presence of a spine at the base of the operculum. They are good swimmers and live alone or in small groups, close to shelters such as caves and coral overhangs. As angelfish are highly territorial, they react badly to other members of their own species. The coloring of the juveniles gradually changes when they reach 8-10 cm though this is not a general rule , and turns into that of the adults. Juveniles adapt...
Palaemonidae
This family includes the familiar pink shrimp, as well as a large number of freshwater tropical species, such as the genus Macrobrachium which covers some 200 species . These long-pincer shrimps are sometimes raised for restaurants this is the case with M. rosenbergii, which grows to 25 cm, without counting its pincers. It is the smaller species that are sold in the aquarium trade, with M. lanchasteri being the most common at the moment. Native to South-East Asia, it acts as a garbage collector...
Chaetodonauriga
One of the best-known butterflies, the auriga is characterized by the adult's filamentous extension of the dorsal fin. Active and not prone to shyness, it is easy to acclimatize. Feed it with living or frozen food, backed up by vegetable material if there are no algae to graze on in the decor. Size 14 cm. accepts food of animal origin backed up with vegetable material. The black patches on the young dorsal area and rear get bigger in adults once they have reached 7 or 8 cm. Size 20 cm....
Lutjanus sebae
The red emperor snapper lives close to corals. The adults, which are often solitary, are not always able to tolerate each other. This species must be put in a large tank with suitable hiding places. Size 20-30 cm. Lutjanus sanguineus The blood red snapper has a good appetite and appreciates small fish. The juveniles have a dark band running from the eye to the base of the dorsal fin, but this is not very evident in adults. Size 30-35 cm. The yellowtail snapper is native to the tropical...
Cyprinidae
Widely distributed over the planet the Cyprinidae barbs, danios, rasboras, labeos, carp, etc. form one of the largest freshwater families, with more than 2,000 species. The smallest species - only a few centimeters in length - are very well known and extremely popular with hobbyists. The largest, which can grow up to 1 m in length, constitute an important human food source the annual captive production of various types of carp - the most familiar member of this family -exceeds 6 million tonnes,...
Characidae Characins
The majority of characidae commonly known as Characins over 1,000 species in all live in South America, especially in the Amazon basin, but not all are aquarium fish. You can usually identify them by a small adipose fin situated between the dorsal and caudal fins however, this is not always present, and is also found in certain catfish species. Their solid teeth indicate that they are carnivores their diet consists, among other things, of insects and insect larvae. Characins live in groups or...
