sera has been manufacturing innovative and high-quality products for aquariums, garden ponds, and terrariums for over 50 years and is one of the world's leading manufacturers in these fields. Founded in 1970 by Josef Ravnak, the family-run company has grown from a one-man operation into an international provider with distribution in over 80 countries and global branches.

The product range includes food, care, and technical products that stand for quality "Made in Germany." Strict quality controls and compliance with Good Manufacturing Practice (GMP) ensure the highest standards. The feed, which is exclusively produced at the company's headquarters in Heinsberg, consists of high-quality raw materials, is free from artificial colors and preservatives, and is characterized by particularly high digestibility. Thanks to short transport routes, products reach retailers in the shortest possible time after production—ensuring maximum freshness and shelf life.

To support trading partners and veterinarians, the sera Academy offers free training and seminars that provide valuable expertise. This expertise makes sera a valued partner for aquarists, terrarium enthusiasts, and garden pond lovers worldwide.
