The holotype was reared from 10 June 2002 until 4 February 2005 in a laboratory aquarium. It accidentally crawled out of the aquarium during the night and died. It was dissected and many mature eggs were found in its abdominal cavity. The mature eggs were between 0.8-1.2 mm in diameter, and batch fecundity was about 20,000 eggs. Under microscope, there was the other immature egg group in its ovaries, the diameters of oocytes were about 0.15-0.26 mm. The paratype was also reared until its death on 22 September 2008. Under the microscope, its gonads belonged to immature ovaries, with 2 groups of oocytes with different egg diameter interval ranges: the larger group was 0.17-0.26 mm, while the smaller group was 0.07-0.13 mm. The two specimens were fed with fish and squid meat (Ref. 127463).
