I have a white comet goldfish and an orange one. The white one is two and a half inches long and the orange one two and a quarter inches. any idea how old they are? and does anyone know how to tell the difference between a male comet goldfish and a female? I'm intersed in breeding my fish.
Hi! How long have you had them? What size tank are they in? Sexing goldfish can be difficult even in ideal conditions. If you just purchased them, they are juveniles. They need to be sexually mature, of breeding age & size. This typically takes 2-3yrs in ideal conditions (50+g per fish or a large pond). Please ask if you have any questions!
I just got them and there in a 20 gallon tank
Thanks! Well, they will need an upgrade in the very near future to prevent stunting or you may want to consider rehoming them to a happy pond & consider fancy goldfish instead. Fancies still need lots of water though- 20g for the first fish, 10-20g for each additional fish but not quite as much as comets which can grow well over 12inches & need tons of water. Ill post a link on goldfish growth so you can get a visual idea of how big they get as well as link on sexing mature goldfish. Make sure you read the articles on the top of this page regarding the 'nitrogen cycle' if your tank has not been properly cycled yet. If you have any questions, just ask!
