Cyprichromis sp. „Leptosoma Jumbo” Mpimbwe Yellow Head – a victim that becomes a tormentor - Magdalena Kwolek-Mirek, Przemysław Mirek;
(...) Cyprichromis sp. „Leptosoma Jumbo” lives in open waters at the range of 5 - 40 m (Konings A., 2005), along the rocky shores of the south part of the Lake Tanganyika . It is distributed in the region covering area between Kanoni in Democratic Republic of the Congo on the western coast of the lake and Mpimbwe in Tanzania on its eastern coast. (...) Cyprichromis sp. „Leptosoma Jumbo” live in big groups and display shoaling instincts – sometimes they create huge shoals together with other fish of Cyprichromini tribe, for example with C. leptosoma, C. coloratus, C. pavo or even with fish of Paracyprichromis genus.
Riccia fluitans – beauty and the beast - Łukasz Kiepas ;
(...) Crystalwort is often sold as a floating plant. Many aquarium hobbyists believe it can become bothersome. Crystalwort may be kept submerged and is planted in such a way in Japanese-style aquaria. Takashi Amano claims it should be planted in exactly the same way as widely known Java moss or the more and more popular Fissidens fontanus. The assortment offered by his company – Aqua Design Amano – includes special stone serving as a layout material to fix crystalwort on it with a thread.
Breeding coloration in freshwater fish found in Poland - dr hab. inż. Roman Kujawa, prof. UWM
Most of the fish species do not demonstrate sexual dimorphism – that is there are no physiological characteristics helpful in telling male from female of the species. The issue looks quite different in the breeding period, especially in the spawning period, when we are able to intravitally determine sex of the specimen on the basis of its secondary sex characteristics such as different body coloration, shape and size of fins or the change in head shape.
Three of the once popular cichlids: firemouth cichlid (Thorichthys meeki), convict cichlid (Archocentrus nigrofasciatus) and T-bar cichlid (Archocentrus sajica) - Sławomir Siudakiewicz;
The popularity of medium-sized cichlids found in Central America and South America has recently decreased – less and less often they appear in our aquaria. It is difficult to unequivocally state the reasons of this phenomenon. They are easy to keep, their shapes are attractive, and provided they are fed properly they become beautifully coloured. They don’t need any particularly big tank – all hereby presented species do well in ca. 70 L aquarium.
„Malawi punk ” Copadichromis sp. „virginalis gold” - Mariusz Suwalski
(...) Copadichromis sp. „virginalis gold” is found in nature in the intermediate zone between rocky and sandy floors – at the verge of rocky shores, where the sandy floor is dotted with huge rocks. (...) Copadichromis sp. „virginalis gold” does not place any burden on the hobbyist by its behaviour – it is a relatively peaceful fish, both when kept in group consisting of members of its own species and when kept with other tankmates.
How to feed discus and what to feed them with - Andrzej Sieniawski;
Proper development of newly bought young fish and maintaining adults in good shape depend, among others, on the type of food and the feeding method. Well chosen food, appropriate for the fish of the given species as well as an appropriate daily dose result in achieving desirable effect. Under such conditions, provided the genetics doesn’t prevent it, in the period of the most intensive development fish achieve bigger size, are more disease-resistant and spawn more eagerly later on.
Iguana. Green dragon in the terrarium. Part I - Witold Borkowski;
(...) Iguana genus includes two species: Lesser Antillean iguana (I. delicatissima), endemic species found on few islands of the Lesser Antilles and green iguana (Iguana iguana) divided into two subspecies – southern one (I. i. rhinolopha) found in the region covering area between southern part of Mexico and northern part of Costa Rica and nominal one (I. i. iguana) found in the region covering area between Costa Rica and southern part of Brazil.
Study of the tarantula and scorpion species. Part 6. Avicularia genus – life in arboreal gardens - Sebastian Żmudzki;
(...) Tarantula spiders are one of the numerous invertebrates found in South America. The members of Avicularinae subfamily inhabit the realm of tree crowns. These fast animals move dexterously among the branches and are capable of long jumps (with the exception of secondarily terrestrial Ephebopus genus). They build their funnel-shaped shelters among the branches. They actively hunt during the day. The spiders of Avicularia genus are widely kept by terrarium hobbyists in Poland. The numerous enthusiasts appreciate the fact that they are docile, easy to keep and beautiful (...) Avicularia versicolor, A. avicularia and A. metallica are one of the most popular and longest known species.
Lawson's dragon. Part II - Alicja Papiór, Szymon Najdora;
Lawson’s dragons are omnivorous. When they mature, they tend to eat vegetable food more eagerly, but young dragons also like to nibble on greenstuff, especially if they were fed with it by the breeder. (...) It is easy to tame the Lawson’s dragons and adults strongly trust their owner. The activities connected with maintaining the terrarium seem to be interesting for them – they allow the terrarium owner to handle and take them out of the tank.

Food additives and the role of roughage in fish diet - Wojciech Górecki;
The percentage of pet foods containing flavours is increasing. Foods are enriched with additives that give them a particular taste or smell as well as with other modifying additives. Some of them, such as flavours, sweeteners or colorants change the food characteristics irrelevantly, significantly improving their palatability at the same time. Others allow to elongate the shelf life of the product. Other additives, although added in small doses, play different regulatory functions and influence numerous processes in the organism.
Nannostomus mortenthaleri (coral red pencilfish). Crimson glimmers in the aquarium - Radosław Bednarczuk;
Let’s imagine fast moving shoal of tiny, marvellously coloured fish: this is how a group of Nannostomus mortenthaleri kept in aquarium can look like. This recently discovered species due to its bright coloration quickly became successful among freshwater aquarium hobbyists. From the article below you will learn how to keep these fish and get to know interesting facts concerning their breeding. Nannostomus genus (from the Greek nanno = 'small' - stomus = 'mouth') belongs to the Lebiasinidae family and is closely related to characids. The genus was already erected by Günther in 1872 and currently covers more than ten scientifically described species.
