Description
THINK fish
The official Biotope Aquarium Project T-Shirt celebrates the philosophy behind responsible and natural aquarium keeping.
The front features the message “THE BEST AQUARIST in the world”, while the back carries “THINK fish”, the famous slogan associated with Heiko Bleher and his approach to aquariums and aquatic life.
For Heiko Bleher, “THINK fish” was a simple but powerful invitation to put the fish first. Instead of thinking only about how an aquarium looks to us, the aquarist should think about the fish: where it comes from, how it lives, the water it inhabits, its natural environment, its behaviour and the ecological relationships that shape its habitat.
This philosophy is at the heart of the Biotope Aquarium Project and the biotope aquarium concept: understanding natural aquatic environments and creating aquariums that respect the biological needs and natural conditions of their inhabitants.
Wearing this T-shirt is therefore more than showing an interest in aquariums. It is a statement of an approach to the hobby:
THINK fish.
Understand its habitat.
Respect its nature.
The T-shirt features the Biotope Aquarium Project logo and website on the back, together with the THINK fish message.
