Enhance Your Colors Naturally

NatuRose Logo

NatuRose™ is a natural source of the carotenoid pigment astaxanthin, derived from a unique strain of the microalgae Haematococcus pluvialis grown under controlled conditions on the island of Hawaii.

Carotenoid pigments manifest themselves as the brilliant hues of yellow, orange and red found in the tissues of aquatic organisms. Carotenoid pigments are largely derived from phytoplankton and the algae, including seaweed and kelp. Captive-bred fish (and therefore the majority of aquarium fish) are unable to produce these pigments de novo and must rely upon carotenoids absorbed from their diets.

The Science Behind Nutrition

The largest percentage of the carotenoid fraction of NatuRose consists of astaxanthin, with lesser amounts of the pigments cantaxanthin, lutein, and beta-carotene. Carotenoids are generally associated with the flaming orange, lobster-reds, and striking yellows found in ornamental fish.

Less widely known is that when carotenoids form complexes with lipids and proteins, they also express themselves as the blues, greens, purples, and browns of the aquatic world.

At Brine Shrimp Direct, we ensure that our diets provide not only the necessary proteins and lipids required for optimum growth and genetic expression, but we also take the additional measure of providing natural sources of carotenoid pigments, such as NatuRose and spirulina, in our premium diets, so that you can realize the full expression of colors in your aquarium.

Product Description

NatuRose has been carefully formulated into a fine, free-flowing dark red powder and is used as a pigmentation enhancer and nutritional source for a variety of freshwater and marine species.

This additive has been successfully used as a source of pigments in aquaculture in such species as shrimp, rainbow trout, and coho and Atlantic salmon. It has produced demonstrable results in the pigmentation of koi and many varieties of ornamental fish.

For additional perspective on astaxanthin and its role in aquatic nutrition, see our article on NatuRose.


The recommended use for NatuRose is as a feed ingredient or dietary component. NatuRose can be readily mixed, blended, extruded, or pelletized with other feed components. A daily ration of 1 part NatuRose to 500 parts feed (0.2%) is equivalent to 35-40 ppm astaxanthin. Studies have shown color enhancement in tetras, cichlids, gouramis, danios, and other species within one to three weeks.

To provide a complete diet, which includes NatuRose at 300 ppm, try our Plankton Gold Flake, Brine Shrimp Flake, or vegetarian Spirulina Kelp Flake. For something new, try PhytoPlankton Plus and ZooPlankton Plus from a new leader in aquarium nutrition, Apeladae Diets. For reef tanks, use our Tahitian Blend algae paste, which also contains NatuRose.
