Aquarist for almost 40 years, Henri Bak raises discus and reproduces wild discus; he is particularly fond of the Heckel and Santarem discus.

Lover of the Amazon, he has more than 20 expeditions under his belt. He is familiar with the Para region (a state in northern Brazil) and has traveled from Tapajos to Nhamundã via Peru, which has allowed him to have a good knowledge of local igarapes.

He has been judge for several discus competitions in France in Ablon, Vincennes, Bretteville, Arvert and Belgium, in Antwerp.

As President of the Jury of the Paris Grigny Discus Show, it is his job to “drive” the judges team impartially.
