Two Small Goldfish In 10 Gallon Tank

    I have two very small common goldfish in a 10 gallon tank. I am looking to upgrade and put them into a 50 gallon tank. Is that plenty room for them to grow to their fullest size?

    Also, I have two gouramis in a 5 gallon tank and will be placing them in the 10 gallon once the two goldfish are out of there. Is that a good idea?

    No, and no. The goldfish will only reach their fullest potential in a pond. But they do tend to only grow to their environment so theres that. (Youd be looking at about 6' max in a 50)The 2 gourami need at least 20g for sure.

    Agree both a no. Comet goldfish can get HUGE. And the gouramis sometimes fight and need at least 10 gallons each. I have two in my 20 gallon and they still then bicker. So im moveing one to a 10gallon.

    Keep them in your 10 gallon tank and enjoy the view. Look to other fish to populate any larger tank you buy.

    The minimum for singletails is 180 gallons. These guys get massive and need plenty of room to swim.

    No to both. No goldfish will thrive or even survive in 10 gallon, especially not single-tails as they can reach nearly 18".

    As for the gouramis, they should each have their own 20 gallon, or share a heavily planted tank of 50 gallons or more.

    What kind of gourami do you have?
