Freshwater Fish
Red Spot Silver Dollar.
A tall, mirror-bright silver dollar marked with red — a fast schooling fish related to pacu. Peaceful in a group but big and active, and a determined plant-eater; keep a school with tough or artificial plants in a 75-gallon-plus tank.

Good tank mates
Semi-aggressive only in the sense that it's big, fast, and best in a school; it needs similarly sized, not-timid tankmates and isn't suited to a peaceful nano community. Good company includes other large peaceful schoolers, bigger barbs, larger catfish, and peaceful cichlids that won't bully it. Avoid small fish it can startle or that get nipped in the rush at feeding, and skip live planted setups, since silver dollars are determined plant-eaters; use tough or artificial plants instead.
Good to know
Red spot silver dollars are closely related to pacu and, like them, belong to the same broad group as piranhas, though silver dollars are plant-eaters rather than predators.

Bristlenose Pleco
Peaceful bottom-dweller that occupies a completely different zone than the mid-water silver dollar, shares South American tropical water parameters, and causes no competition or conflict.
Bronze Cory
Small, peaceful schooling catfish that stays near the substrate well out of the silver dollar's mid-water swimming zone, sharing similar soft, slightly acidic water needs.
Clown Loach
Peaceful schooling loach native to Borneo and Sumatra that occupies the bottom while silver dollars swim higher. Despite being Southeast Asian rather than South American, water parameters align well — both species thrive in warm (77–82°F), soft, slightly acidic water — and temperament is fully compatible.
Green Severum
One of the more peaceful South American cichlids and explicitly recommended as a silver dollar tankmate across multiple cichlid care resources. Similar adult size prevents bullying, and both species share compatible tropical water parameters. Monitor during breeding periods when severums can become temporarily territorial.

Kuhli Loach
Slim, peaceful bottom-dweller that hides by day and poses no threat to the larger silver dollars living above it in the water column. Multiple silver dollar tankmate guides endorse this pairing; silver dollars are herbivores and will not predate kuhli loaches. Provide ample caves and driftwood to keep the loaches stress-free.
