Tank compatibility[edit]

Should only be mixed with large brackish fish, such as Monodactylus and Toxotes. Caution should be taken even with large fish because they are scale nippers and do extensive, but not deadly damage to broad

bodied non-aggressive fish like Scats. However, a sufficiently large tank with hiding spaces is needed to ensure that no one particular fish is frequently targeted for scale nipping. Most scale nipping may occur at night.


In the wild, feeds on fish, invertebrates, and detritus, but will accept pellets in captivity.

Feeding regime[edit]

Once or twice a day on dry foods and frozen foods, every other day on meaty foods.

Environment specifics[edit]

Keep in brackish water, SG around 1.005 to 1.015; and hard, alkaline water. Temperature around 24-28°C (75.2-82.4°F) . The SG can go to full seawater strength up to 1.025.


May be predatory towards smaller tank mates, as well as occasional nipping of other fish. Will eat fish 1/4 to 1/3 their size!


Mostly silver, with almost curved bands running horizontally across the sides; looking like an archery target from above. Tail banded with black. Large, sharp dorsal fins. Not to be confused with Terapon theraps, which has completely straight lines across the flanks.
