Sora Posted June 17 Share Posted June 17 I had always wanted goldfish and I finally decided to start a project to get some. Their gonna be in a 40 gallon stock tub (because tanks are expensive). Im mostly sure the floor will support it on the second floor right? I am gonna get 2 juvenile ranchus, I've heard that 40 gallons would be the minimum for 2. thoughts? https://kingkoigoldfish.com/products/613rptc-114 Link to comment Share on other sites More sharing options...

Cinnebuns Posted June 18 Share Posted June 18 It is true that most articles you will find through using Google will say 30 gallons for 1 and 10 gallons for each additional however most people you talk to say much more than that. One problem I have found is that most of those articles are either written by bots or people not even in the aquarium hobby. I have learned to not trust them. I can't give you a specific answer other than that as I am not a goldfish person. I just know that I have never seen someone who is a goldfish person recommend less than a 55 gallon. 1 Link to comment Share on other sites More sharing options...

I know that 40 gallons is a little small, but I have researched and watched some videos (mostly by Luke’s goldies, who is a goldfish breeder) recommend 20 gallons per fish. Also I plan on filtering with 2 sponge filters rated for 50 gallons each and doing weekly 50% water changes. So I don’t think I will really have to upgrade, but I might anyway. I’m pretty sure 40 gallons is enough for them not to get stunted. Also I know bigger is better and I would, but big tanks are very expensive especially because you need to get a stand for them. https://lukesgoldies.com/blogs/news/complete-fancy-goldfish-care-guide Edited June 18 by Sora Link to comment Share on other sites More sharing options...
