Welcome to Viscum Water Gardens and Aquatics. A family owned business specialising in fish, aquariums, ornamental ponds, associated equipment and maintenance for over 35 years.

Business partner and founder Paul Ryan has run operations and managed the company since its establishment in 1980. Paul started it all way back in the late seventies as a teen by developing his interest in keeping aquatics to breeding and selling off his produce. To Viscum, providing good quality service and advice has always been of paramount importance, which is why all Viscum employees thrive to ensure the best quality advice is always available.

We cater for everyone, from specialists to novices and our livestock ranges and fishkeeping equipment are second to none.
