Family description (Nemipteridae)

The Threadfin Bream (Nemipteridae) is an often overlooked fish by aquarists, they are both attractive and interesting to keep in an aquarium, as long as one can provide them with an appropriate environment.
The substrate colour can influence their appearance. They are by far the most attractive with a dark substrate.

These fish like to eat food from the bottom and until they get used to eating in the water column, it is vital to be certain they obtain enough food from the start.
As they grow larger, they can become a threat to small crustaceans and small fish.
