Goldfish Fry Color Development: Brown with Red Fins

Goldfish Fry Color Development: Brown with Red Fins

Large pond goldfish bred 2-3 years ago. Fry now 5-6", brown with dark red fins. Owner also has mirror carp, shubunkins, roach, rudd. Asked if color is normal.

Normal Color Timeline

• Most goldfish color up at 1-3 inches.
• Some hold wild-type brown/camo to 10+ inches.
• One case: color change at 10 inches.

Red Fins: Unusual

Dark red fins not typical. Common progression: brown → orange/black fins → orange → orange/white fins. Red eye rings seen in whites.

Possibilities

1. Hybridization: With carp, roach, rudd? Unlikely but possible.
2. Genetic variant: Unique strain expressing red fins.
3. Diet/environment: Carotenoid-rich food can enhance reds.

Identification

Check against roach/rudd (color up small). Photos would help confirm.

Brown at 5-6" is within normal variation. Red fins are interesting—possibly a unique genetic line. Share photos if possible.
