Today, we can distinguish several types of feed for ornamental pond fish:
Light fish food(for winter);
-Fish food with spirulina (for immune support);
-Feed to improve the color of fish;
-For the reproduction of fish.
Under a multi-year experience of maintenance of water bodies, including populated and unique, sometimes a collector’s breeds of ornamental fish, we have allocated a professional complete feed ASTET made in Holland. Feed ASTET appeared on the market relatively recently. Our choice is motivated a good adaptation and acclimatization on virtually any kind of ornamental fish to new conditions of living.
Typically, the most interesting specimens of ornamental fish originate in Southeast Asia. In this regard, a good adaptation and acclimatization to ours, is far from simple to ornamental fish species the conditions out in the first place. Feeding, is crucial for adaptation and acclimatization of fishes. Fish with pleasure eats food ASTET all season and has a great feeling. Continue reading
