Dennerle Shrimp King Color is a sinking, water-stable feeding granulate consisting of 100% natural ingredients. Colour-boosting effect for yellow-, orange- and red-coloured shrimps. Contains a high level of natural, colour-boosting carotenoids, such as astaxanthin, beta-carotene and lutein. Yellow, orange and red shrimps cannot develop the colours that give them their attractive bodily colouration themselves, and they have to take it in via their food. These colourings, called carotenoids, are primarily found in algae, flowers, fruits and leafy vegetables. Shrimps and crayfish turn carotenoids into their own colourings, especially astaxanthin, which forms a molecular bond with the protein beta crustacyanin. These molecular compounds are stored in special colour cells and give the shrimps their species-specific colouring. Shrimp King Color is especially suited to the following species: Red Fire, Sakura Red, Sakura Orange, Blue Pearls, Yellow Fire, Black Tiger Shrimps and Blue Tiger Shrimps.
