I added a Uaru to my 55-gallon planted tank with other South American species. It’s been two months and it’s very calm, doesn’t chase other fish, and looks stunning with the live plants. I keep the temperature around 82°F and have not had any issues with diseases so far.

The fish arrived healthy and quickly settled into the tank. I was a bit worried about cichlids being aggressive, but this one is very gentle. I’ve noticed it spends most of its time near the middle of the tank, not near the edges or decorations.

Beautiful fish with a unique shape. I love how it blends in with the Amazon-themed setup. Water temperature is maintained at 84°F, and it’s thriving. No signs of stress or illness after three months.
