The red and white coloration is very vibrant and stands out in the tank. My Ryukin has been thriving for over a year in a 30-gallon aquarium with other fancy goldfish. It’s active but not aggressive and adds a lot of visual appeal.

Beautiful fish with a unique pattern. I noticed each one has slightly different color distribution, which is charming. The tank needs regular water changes, but overall, it’s a satisfying addition to my home aquarium.

I bought this as a gift for a friend who loves fish. The fish looks stunning and is very calm. It’s been living in a 20-gallon tank with a good filter and has adapted well to the environment.
