If you have questions about rules of the contest, feel free to send them to contact@biotope-aquarium.info

Anyone can participate in the contest, regardless of citizenship, nationality and place of residence. The contest rules are the same for everyone. Each participant has the opportunity to submit up to five biotope aquaria to the contest. We accept only freshwater biotopes.

The aquarium should be a copy of the natural biotope. Its title should contain: the name of the water body, place where biotope is located and country. For example, Lake Chad. South Beach, near the village of Sangria. Chad

How the biotope aquarium was recreated based on the natural habitat. So you should add a description (100 to 300 words), which may contain details about the underwater landscape, colour of the ground, stones and driftwood. Specify species found in the natural aquatic biotope, not used in your aquarium, but influencing the ecosystem. You can also specify hydrological and ecological characteristics of the water body, information about the threat of extinction of species.

In your biotope aquarium there should be only aquatic organisms that live in this nature habitat. Please specify the actual Latin names of fishes, invertebrates and plants. Cosmopolitan and invasive species in the list are permitted only in the case of detailed explanation in the description of your biotope and (cosmopolitan / invasive species) written in brackets after the Latin name. All aquatic organisms mentioned in the list should be visible in the photos.

Please specify the information sources that were used for study of your biotope. Books: title, author; article: title, author, issue or a link to an article; video: title and link; page in social networks; author or group name, a link; personal study of the biotope in nature; copy of another aquarium: information about its author. If possible, please specify more information. This will help the jury to evaluate your aquarium more accurate.

High-quality photos are one of the most important components of successful participation in the contest. You are allowed to upload to your contest form up to six photos in a resolution of at least 2000 pixels by the longest side in JPEG graphical format. Each file should not exceed 10 megabytes. Blurred, fuzzy photos and photos with easily distinguishable defects are not allowed. The author can crop original photos (1) by the front glass of the aquarium (2) if there are plants above the water in it. ATTENTION! The members of the jury will evaluate only underwater part of your aquarium (3). The part above water can only affect the overall impression. The organizing committee can re-crop your photo, if your crop does not meet the specified conditions. Additional drawing and cloning parts of the photos are not allowed! If the organizing committee members or the members of the jury suspect that editing was used, the participant will be disqualified immediately. Colour and white balance correction are allowed only to compensate shortcomings of your photo.
