Maintenance and Care
The Flagfish tends to inhabit shallow, slow-moving waters that are densely planted. These fish can sometimes be found in swamps, backwaters, and marshes and they have even been found in brackish waters. These fish prefer a temperature range between 66°F and 72°F with a pH between 6.7 and 8.2 and a water hardness between 6 and 20 KH. They should be kept in densely planted tanks with driftwood and rocks for decoration and dark substrate to bring out their coloration.

This is a mid-range fish for the most part, though it will sometimes feed on decaying plant matter and algae in the aquarium. These fish will eat just about anything, including flake foods and pellets as well as live, frozen, and freeze-dried foods. Feeding these fish a rich diet of high-quality foods will help to bring out its natural coloration.
Flagfish are egg layers and they are generally not difficult to spawn in the home aquarium. Females of the species are larger and more full-bodied than males, plus they have a little more yellow in their coloration. During spawning, eggs are generally released individually or in small batches on various surfaces including plants and tank decorations.
