Sturgeons are very special fish. Their body shape indicates their way of life: They swim near the ground and use their barbels (chemosensor organ) to feel for small invertebrates, which they would eat in the wild. JBL ProPond Sterlet has been adapted to suit these eating habits, both in its composition (increased share of invertebrates) and in its sinking behaviour. Even if sturgeons can learn to feed at the water surface, this feeding behaviour doesn’t represent their natural behaviour and harbours the risk of excessive air swallowing. Sturgeons should always be fed with their own food because it has a dedicated composition and the sturgeons could hurt the koi’s mucous membrane with their bone plates when fighting for their food. In practice you can feed your goldfish and koi on the surface at a corner of the pond and your sturgeons with sinking sturgeon food at the other corner.
