Copepods! If you want a mandarin dragonet, you've heard that you need them. Copepods are one of the smallest living thing we can observe in our reef tanks without a microscope, and even at that; they require a fine eye! We propagate 3 species here at RRA, and a bottle of TNT copepods includes two of the most popular, tisbe biminiensis and tigriopus californicus. apocyclops panamensis are also available in both large and small quantities for the price of a standard mixed bottle. These tiny powerhouses are great for LPS corals and many fine choices of live stock.
