Overview

The silver tiger perch is a mostly peaceful predator that holds the middle of a large brackish or freshwater tank. It needs a keeper with some experience.

Did you know

The silver tiger perch tolerates a wide range of salinity. That makes it the tiger perch most often seen in the hobby, and the easiest of the group to keep.

Caring for the silver tiger perch

Give a silver tiger perch a tank of 79 gal (300 L) or more, with driftwood and open space. Strong filtration and clean water keep it healthy.

It does best in brackish water with a specific gravity around 1.005 to 1.010. Keep it at 75 to 82°F (24 to 28°C) and a pH of 7.0 to 8.0. Feed meaty foods such as shrimp, prawn, earthworms and the occasional piece of fish. Move juveniles off live feeders onto frozen foods.

The silver tiger perch is more social than its relatives. Unlike the pure freshwater tigers, it can live as a small group in a large enough tank, which spreads out any aggression. A group often looks better than a single fish. It is a predator that eats smaller fish but ignores tank mates too large to swallow.

Good to know

The silver tiger perch, Datnioides polota, belongs to the family Datnioididae. It was formerly known as Datnioides quadrifasciatus. It carries silver sides with dark bars.

In the wild

The silver tiger perch is the most widespread of the tiger perches, from India through Southeast Asia to New Guinea. It lives in tidal estuaries and lagoons as well as coastal rivers, moving between fresh and brackish water. It holds midwater among wood and structure.
