The Brazilian Aquascaping Contest or CBAP is the most traditional and oldest aquascaping contest in aquariums in Brazil. It had its first edition in 2004, being today the most important aquascaping contest in Latin America. It was one of the pioneers in the world, along with the international references IAPL (International Aquatic Plants Layout Contest), organized in Japan by Aqua Design Amano and the AGA Contest, organized by the Aquatic Gardeners Association, in the United States.

Since its inception, our contest has grown, receiving an increasing number of entries and in 2012, it conquered its position in the international calendar of contests of its kind, starting to receive international entries in an exclusive category for foreigners.

In 2013, the CBAP award party was named EBA (Brazilian Aquatics Meeting) and began to bring together not only planted aquascaping practitioners, but also aquarists from different areas, including freshwater, jumbos, cichlids and marine aquarists.

We want to unite all nature lovers and further strengthen our hobby, showing that everyone has space and must be respected and publicized. We hope that in this way we can unify our efforts and walk together in the solidification and development of Brazilian aquarism.

We count on your participation, disclosure and presence.



Starting Date: The contest opens on July 1 (Brazil GMT-3) 

Closing Date: August 31 (Brazil GMT-3)

In case of doubts to prove suspicions regarding the content of the entries submitted to the Judging Panel, the Contest Organization determines that:

- The counter-proof in case of image editing must be made by additional images of the aquarium sent by the participant, containing the entire aquarium or details, where the disputed point is shown and attests to the veracity of the submitted photos.

- The Contest Organization reserves the right to accept or not the reproof and its decision is irrevocable.

- The counter-proof in case of ownership of the assembly must be made by images or documents that attest to the ownership or execution of the layout by the registrant.

- Never leave your registration in the last week, technical problems can occur due to the receipt of an excessive number of registrations and the organization of the contest will not reimburse the registered in any way, if your registration is not made.

- The organization of the contest reserves the right not to provide any other details regarding the judgment of the entries.

- Since the only means of proof and visual evaluation of the entries is through the photos provided at the time of the participant's registration, it is common sense that the photos must be of sufficient quality for verification (See item #2).

- Low quality photos, blurred, smudged, with traces of excessive electronic editing or any other characteristics that prevent their evaluation by the members of the judging panel, will invariably harm or even eliminate the work of the contest. Before sending any information, check the veracity of the material that is being sent, as it will be analyzed by the judging panel of the contest.

- The Contest Organization may, at any time, ask the registrant for proof of ownership of the aquarium, such as specific photos, sending material by mail, etc. If ownership of the aquarium is not confirmed, or if the use of other people's photos is confirmed, the aquarium will be automatically disqualified, and its position will be occupied by the next in order of classification. Insistence on disrespecting the contest rules may result in the disqualification of the participant and all of their registered aquariums.
