My wife and I were at Thomson Plaza and Aquatic Concepts just now to buy three leopard corys and saw that Dennerle has setup an mini-exhibition of its products (accessories, materials, nano-cubes, stands) on the ground floor. The floorspace for the exhbition isn't very big; perhaps the size of a normal Bata shop - but there're a number of tanks on display, including demonstration setups. The exhibition is jointly run by Aquatic Concepts and Dennerle from what they told me when I asked.

If you're in the vicinity or stay near, it could be worth a look. The exhibition runs till the 6th May.
