Origin.
 Coming from the tropical waters of the Amazon River, you know these big cichlids need warm water.  Coming from the black waters of the Rio Negro also means they need water with a low pH.  Somewhat rare, we seldom see uarus on the market except as juveniles from the Orient.

LA
At one inch, these cute uarus really catch your eye.  Compare size with the suction cup.

Juvenile Appeal.  Looking very much like many other larger cichlids when full grown, most people are attracted to the juvenile uarus – which look quite similar to a leaf fish sprinkled with white stars.

Slightly Larger Stage.  At two inches they start losing their juvie polka dots and begin to look very much like their parents.  For some reason they get a bit shy at this stage.  They hang to the back of their tank -- until you feed them.  They like to look for food on the bottom.

 

 

Adult Appeal.  Some people can’t resist a challenge.  Keeping uarus in Des Moines water gives you exactly the same challenge as keeping discus in our moderately hard, high pH water.  You may need to adjust the pH and dissolved lime levels in our water.  Just install a reverse osmosis water system and you’re on your way.

Size.  Inch-long uaru juveniles grow into hefty foot-long bruisers looking similar to severums but with a larger mouth.

LA
When small, they like to hang together.

Space.  You can keep one uaru in a 30-gallon tank.  However, you really need a 55-gallon tank to house a pair comfortably.  You could probably even crowd four in there.

Water.  You can often keep your uarus healthy in our “moderately hard” pH 7.5 Des Moines water.  However, if you decide to breed them, you need to lower your hardness and pH level.  Remember that soft water usually cannot maintain a stable pH.  Use one of the discus buffers to stabilize your water chemistry.

Foods. Give your uarus a variety.  Yes, they eat flake and frozen foods.  Add some snails to clean up any excess food that falls to the bottom.  They snack on duckweed.  They go slightly bonkers for live California blackworms.
 

LA
They ate the sword plants and ignored the cryptocorynes.

LA
They totally ignored these cryptocorynes.

Plant Eaters.  If you decide to add live plants, get cheap ones.  Uarus love to eat plants.  These eager eaters like some plants better than regular fish foods.  Like African cichlids, they would probably refuse to eat Java lance fern and Java moss.  If you want a jungle look, you will probably need plastic plants.
 

LA
Whoops scratch the Java fern idea.  They shredded this.  Plant plastic plants.

Disease.  Expect the same disease problems that affect discus.  See Discus for more info.

 

Breeding.  You will need lots of room if you intend to breed your uarus.  Isolate your breeding pair and pamper them like discus.  Provide large, rounded rocks and flat slate to give them a choice of spawning sites.

Glancers.  Like discus, chromide, and pike cichlid fry, the uaru newly swimming fry eat the nutritious slime generated on the bodies of their parents.  The uaru fry will not do well if you remove the eggs or fry from the parents.  Add newly hatched live baby brine shrimp after a week or so.

LA Pic
For some reason, little uarus like to school together.

LA Pic
When they hit a massive 1.5 inches, uarus start developing some colors.

LA
They start losing their pretty little dots.

LA
Uarus tend toward neutral colors as they mature.  He is nowhere near full grown.

LA
Nice looking cichlid but not the easiest breed to keep.

LA
Not seen often enough.

Last Comments. Clean water is essential to keeping uarus and other large cichlids.  Change at least 25% weekly.  Add some anacharis or duckweed to help keep your water clean.  Uarus will probably eat both these easily replaceable plants.  LA.
