Ranchu tank

[Dane.w]

I have a fish tank that’s 15 gallons and wanted to know if that is enough space for 1 ranchu goldfish

I believe they need at least 25 gallons. It may work short term but not once it gets big

This is a really debatable topic. I would get a 29 gallon since I personally like to keep goldfish together since they're social. 29 for 2 is a reasonable tank size to me, 40 would be better though.

I breed goldfish although Not during the Pandemic. Anyway, rule is 20 gallons for first fancy goldfish and 10 gallons for each additional one. So a 29G would be fine for 2 fancies. I hate to see a goldfish alone. They need a companion. Mine pile up and sleep together. Don’t buy a comet , Common, Shubunkin, or any single tail goldfish. They are pond fish and get up to 12” in length. I have 3 females in a 75 gallon and 2 males in a 45 gallon.

I agree. Its a torture to huge fish to be keeping them in a small tank.

this is a little off topic but how do you sex goldfish?

mature females are fatter than males.
mature males develop small white dots on the gill covers and pectoral (side) fins when in breeding condition.

I think you can! I have a ranchu too in my 15 gallon outside tank! It does fine! But they will probably need a much bigger tank later in the future! I have seen them fully grown and they can get MASSIVE! But for a year or two, they should be fine in your 15 gallon! Good luck!

I believe that they already should have a bigger tank as they can get stunted.

I personally think as long as you keep up with massive water changes it'll be fine for a while. Fancies are already stunted anyways, and a lot of fish we keep in aquariums are stunted, we just don't realize it(of course I'm not saying keeping the fish in a small tank is good).

If they're not stunted for long they can get re-stunted. Anyways they actually still grow and I think the goldie of the OP should be moved to a 30 gallon as soon as possible to avoid stunting.
