Natural Composition in the Nature Aquarium - Takashi Amano
In the Nature Aquarium a layout is created by placing substrate material in an aquarium first, placing layout materials next, and then lanting aquatic plants. Natural rocks and riftwood are used as layout materials, and these are placed in the aquarium using natural scenery as a reference point..;
General rules of fish disease treatment - prof. dr hab. Jerzy Antychowicz
This article’s author is a decidedly opposed to applying medications at random, not knowing what caused the disease. Very often the non-infectious diseases, caused by bad environmental conditions and feeding improper for a given species become a source of problems in breeding aquarium fish. In such cases applying medications will not only be unhelpful but may also burden the fish’s organism with products of medication metabolism.
Magunga - Wojciech Sierakowski, Marcin Soboń
As it comes to the popularity ranking, the mouthbrooder Metriaclima sp. „msobo”, thanks to the several of its features, routs all the remaining Malawi endemic species. It concerns the colour variety endemic to the Magunga reef from the northeast part of the lake. (...) This mouthbrooder exhibits very distinct dimorphism but both females and males are very beautiful. As the fish is impulsive, defends its territory and exhibits building skills (it is a rock dweller) it has to cast a spell on aquarium fish hobbyists and it is quite effective.
Probiotics in aquarium hobby - Wojciech Górecki, prof. dr hab. Włodzimierz Popek
(...) Microbiological research on taking advantage of different strains of bacteria, widely known as probiotics, became a new trend in aquaculture. Research on ways of utilizing these microorganisms is aimed at two goals. The first one concerns the process of biological conditioning or effective improving of water quality. The second one concerns nutritional issues.
How should you prepare yourself for keeping discus fish? - Andrzej Sieniawski
Despite the fact that discus fish have been scientifically described more than 100 years ago, the history of their mass popularity in European aquaria has practically started at the end of 20th century. (...) When keeping discus fish one has to consider setting the tank of one of the three types: hygienic, semi-hygienic or a planted one. In order to let the aquarium hobbyist make a perfect choice, we have to describe each of the types mentioned above as well as discuss the pros and cons of each method.
Never before have guppies of one variety been available in so many colour variations and never before have they been so colourful. Never before has any other fish raised so much controversy and or has been surrounded by such air of mystery as magenta. (...) Magenta ancestors, Konarzewski’s magenta.

Summer holiday - Sebastian Żmudzki
Tourists that chose to sped their summer holiday in an active way often forget that unlike animals from the northern part of Europe, creatures living in the South of the continent may pose a threat to the carless hiker’s health or even life. (...) We all know the species that is found in our country perfectly well – common European viper (Vipera berus). Peninsulas in the South are inhabited by several species of vipers. The common ones include: asp viper (Vipera aspis) and horned viper (Vipera ammodytes). (...) Among the grass and bushes of the open, sunny spaces one can come across Mediterranean black widow (Latrodectus tredecimguttatus), a cousin of the infamous black widow found in America.(...) Scorpions are another group of invertebrates. (...) Two species from the Buthidae family can pose a real threat: Buthus occitanus and Mesobuthus gibbosus. (...) The former of the two species is more venomous than the latter. It is actually the most venomous scorpion in Europe and is found in Balkan countries and well as in Turkey.
Bearded dragons - Łukasz Kiepas
Last winter I stumbled upon an industrial container made of thick, stainless metal plate. At fist sight it seemed to be an ordinary, old piece of junk. I decided to buy it and turn it into a summertime terrarium for my bearded dragons.
Apistogramma trifasciata and Apistogramma hongsloi - Radosław Bednarczuk
Most of the species from Apistogramma genus are characterized by the fact that very soft and relatively acidic water is indispensable to their proper development. However, it’s difficult for a statistical aquarium hobbyist to achieve such water parameters, especially when only hard tap water is at disposal. Nevertheless, there are two dwarf cichlid species that can be successfully kept in medium hard water with neutral pH. This includes two species that this article is devoted to: Apistogramma trifasciata (three-striped dwarf cichlid) and Apistogramma hongsloi.
Shrimps for anyone - Marcin Graczyk
My adventures with shrimps began several years ago during the Zoo-Botanika fairs in Wrocław. (...) Unfortunately, as I used to be a student at that time, I couldn’t afford beautiful Asian wonders. It seemed the whole experience would be doomed to end before it actually began, or at least that I would be forced to make a year-long break in my shrimp quest. On the contrary – my adventure has just begun.
