Copepods: Tigriopus californicus (Tig pods)

With its high nutrient content and enticing “eat me” dance, Tigriopus californicus, aka Tig pods, make the perfect supplement to your reef’s planktonic feed menu, especially for the picky members of your community tank.


Why T. californicus?

  • High in essential fatty acids (HUFA; 20:5n-3 and 22:6n-3) which cannot be synthesized by fishes and need to be ingested through live prey. HUFAs are needed for growth, reproduction, and development for fishes and shrimp
  • Huge source of nitrogen and phosphorus which help build calcium carbonate exoskeletons if used consistently (important for coral)
  • Faster reproductive rate, flexible diet, and tolerance to different salinities and temperatures vs other copepod species
  • Large body size
  • High in carotenoids (astaxanthin) which help maintain predators’ vibrant colors
  • Hide in the sediment and in aquatic plants so are available to your tank’s feeders 24/7
  • Feed on detritus & algae, so they keep your tank clean while feeding your critters

Critters that love them

  • Wrasses, seahorse & pipefish fry, dragonettes, filefish, basslets, cardinal fish, anthias, cardinal fish, butterfly fish, most corals

Care Tips

  • Acclimate a portion of the T. californicus to the same water temp and salinity as your home tank (our copepods are reared at 20 C which increase the fatty acid content)
  • Feed your tank as needed
  • Short-term: store the remainder of the copepods at a cool temperature; Longer-term: leave them out at room temperature to allow their supplied algal food (present in the culture water from ARS) to continue to photosynthesize. The female copepods tend to eat their young so use your copepods quickly!

 

T. californicus is available in two sizes

0.5 L or 1 L
