    Goldfish are one of those fish thats best ID'd when breeding - or spawning.


    Males however are known to have thicker leading edge on the pectoral fins, which is used in breeding... the pics are a little hard to make out, so if you look online and compare it to your fish, you could find out what it LIKELY is...

    In the warm weather male goldfish get white spots on their gills and chase the females.

    yours might not be mature yet, usually around 12 months.

    like the others have said, its difficult to tell the gender outside of breeding season. but there are some minor differences.

    males will develop the white spots are tubercles on the gill plates and pectoral fins. pectoral fins also longer, thinker, and pointier. the pelvic fin will be thicker. body i usually more slender.

    females generally have bigger and rounder vents. body usually thicker and belly will get rounder with eggs.
