Sera

Sera

The birth of sera took place in 1970. Josef Ravnak, who already had gained excellent reputation with the sales live food, founds his first enterprise and revolutionized the branch by using the freeze drying procedure, which was new at the time. This allowed conserving food organisms such as bloodworms, Tubifex, Artemia shrimps and Daphnia while optimally preserving the nutrients and vitamins.

    Sera Snail Collect

    Sera Snail Collect

    Snails are attractive aquarium inhabitants - provided their number within the biotope is in order. In case of overpopulation they can quickly become a pest. The new snail trap sera snail collect limits the multiplication of the mollusks without any chemical agents! A second, immovable grid consisting of separate bars can be placed in front of the first one. The distance between the bars can be adjusted individually. Accordingly, the sera snail collect can be adjusted to the size of the animals to be caught - at the same time, no fish can enter and, in the worst case, die. The sera snail collect combines simplest usage with maximum safety!
