Dear Biotopers,

BIOTOPE AQUARIUM Project and International Aquatic Plants Layout Contest (IAPLC), international competitions of two different aquarium styles but with the same core, have agreed to respect each other’s educational efforts and creativity.

Starting from February, 2022, BAC and IAPLC steering committee have adapted similar participation restrictions, in order to avoid double entries and to respect the Jury’s evaluation work. According to this agreement, IAPLC contestants with a biotope style entry are not allowed to participate in the BAC and vice versa, BAC participants are not allowed to enter IAPLC or other biotope contests (except BAP authorized contests).

How to particpate?

It’s easy! The participation in the contest is regulated through the BAP Platform. All biotope entries, including photos/videos must be submitted online following the unified procedure for everyone.
