"Fish and other marine organisms cannot synthesize carotenoids themselves and must consume them through their diets. This is difficult as carotenoids cannot be transported through plasma and are not absorbed nearly as much as other nutritious elements. Carotenoids must be absorbed when associated with lipid plasma proteins, or in other words, assimilated into the fat of the consumed organism. Because of this, many synthetic carotenoids are expensive, wasteful and incredibly impractical for feed formulation. Therefore, the most practical route for achieving maximum levels of carotenoids in an aquarium is by having robust colonies of autotrophs, such as Rhodopseudomonas or Rhodospirillum, to actively produce them."

Powerful Pigments: Carotenoids and PNS Bacteria
Pigments are organic molecules of unbelievable power. Bacteria, archaea, algae, plants and other photoautotrophs create pigments to capture photons, thereby deriving metabolic energy from light. Without these miraculous compounds, light would remain forever elusive to biology. There would be no...
