Speaker topic: My Cichlidarium, a personal history

Keeping cichlids on a larger scale requires adequate facilities. Therefore I have created a fish house (the Cichlidarium) that suits my needs, especially for keeping big cichlids. This presentation covers the way to build such a fish house (stands, tanks, water supply, lighting, etc) and closes with a report on some dramatic events that can happen to you on the way.

Willem Heijns

Speaker bio: Willem is a 65 years old retired bankmanager and has been keeping cichlids well over half his lifetime. He started out with the firemouth (Thorichthys meeki) and subsequently has been hooked up with Central American cichlids ever since. Having had small tanks at first he moved onto build his “Cichlidarium” containing two 600 gallon aquariums and some smaller ones. After some major calamities (two 600g tanks exploded almost in his face) the Cichlidarium was finally closed down in March 2011.

Willem has been a member of the Dutch cichlid association (NVC) for over 35 years and has served as their President for well over 12 years.

About 15 years ago he started collecting cichlids in México and other countries in Central America. Most of these trips he made together with Ad Konings and some with Juan Miguel Artigas and Don Danko. On the first trips he focussed on collecting cichlids but on later ones Willem tried his hand at shooting video both above and below water. This has resulted in bringing (new) cichlids into the Dutch hobby and a number of films, a compilation of which is available on the DVD “México, a journey into the world of cichlids”.

His last three trips were made to Nicaragua. He visited most of the crater lakes in that beautiful country searching for cichlids, concentrating on Laguna Xiloá where he put his diver’s license to good use being able to get video footage from depths of 20 meters or more. This footage was edited to produce the DVD “Nicaragua, cichlids from the crater” which is also available to the public.

No longer keeping cichlids, Willem is now concentrating on writing. He has published a number of articles about cichlids in magazines worldwide and has also co-authored a book on these wonderful fishes. His main area of interest is the evolution and systematics of Neotropical cichlids belonging to the tribes Cichlasomatini and Heroini.
