Sexual dimorphism of G. broussoneti is distinguished by a small urogenital papilla, which is in the ventral region between the anal opening and the anal fin. In the females it is short, blunt and has a yellow coloration; in males it is thin, pointed and has a smooth appearance. Spawning is possible in a large aquarium. Harper, in Tropical Fish Hobbyist (#473), documents success in captive spawning on pages 130-132. He suggests using a spawning group of one male and three or more females. The tank should be furnished with hiding places for the females and a nest for the male. The fish should not be fed for a week and then conditioned on live foods. The salinity should be lowered and then raised. The male will spawn with several females over the course of a day. Following spawning, the females should be removed and the male will guard the eggs. After 36-48 hours, the fry hatch and the male should be removed. After the egg sacs are consumed, the fry can be fed roftiers and green water containing algae. After a month, Artemia nauplii can be fed. No other spawnings in captivity have been reported. Questions about reproductive seasonality, ovarian development and spawning of G. broussoneti need further investigation.

Dragon goby (Gobioides brousonnetti) is a scavenger that feed only on smaller food types, such as plankton, daphnia and bloodworms.

The sex of koi fish cannot be determined unless a)you dissect the koi or b)you witness the breeding.
I have been feeding mine sinking pellets. the dragon goby is a bottom feeder.
The dragon goby is semi-aggressive, but mainly feeds by sifting organisms out of the mud. In general, like most fish, they will eat anything that fits in its mouth. A fancy goldfish can reach 10"-12" and a dragon goby can reach 24". It would seem that once the goldfish reached a large enough size, it would be safe. I would not put a 2" goldfish with a 24" goby.
