Research or Links to information on Species:	From Frank's Blog: Two C. kleinii adults were collected as a mated pair off Oahu and conditioned in a 100-gallon tank on a mixed seafood diet. The pair spawned immediately after being introduced to the broodstock tank and then periodically following a 3-month period of photoperiod and temperature manipulation. Spawns of up to 2,500 eggs with 30% fertility were recorded. C. kleinii juveniles were raised from hatchery-spawned eggs in the summer of 2015. The eggs were spherical, clear, contain a single oil globule and measure 0.7 mm in diameter. The larvae hatched at 2.1 mm TL with yellow pigment dots running along the notochord. They began to feed three days after hatching (dph) at 2.6 mm TL. Bony plates, called tholichthys, formed on the head during the late pre-flexion stage. Flexion began near 18 dph at 5.6 mm TL and was completed near about 25 dph (6 mm TL). The larvae had moderate to heavy yellow and dark pigment spots on the body through day 30 at 6.6 mm TL. The body of post-flexion larvae gradually took on a silvery appearance and the tholichthys plates became larger, extending from the head onto the body. The transformation period was long in captivity. The black bar through the eye and the white posterior margin on the dorsal first appeared near 65 dph (12 mm TL), full bottom orientation and juvenile behavior took place by 84 dph (24 mm TL), and complete juvenile coloration and meristic characters were present by 94 dph (27 mm TL).

Other Information:	Everyone was getting real close, Frank Finally did it with captive-spawned eggs and wild plankton. Toughest of the tough.
