* Provide plenty of hiding places. Firefish feel more secure when they have places to hide, so provide plenty of caves, crevices, and live rocks in their tank.
* Reduce stress. Firefish can be stressed by a number of things, including changes in water quality, overcrowding, and harassment from other fish. Make sure to provide your firefish with a stable, peaceful environment.
* Offer a variety of foods. Firefish are carnivores and will eat a variety of foods, including live brine shrimp, mysis shrimp, and frozen fish food. Offer your fish a variety of foods to help them get the nutrients they need.
* Try hand-feeding. Once your firefish has settled into its tank and is comfortable with its surroundings, you can try hand-feeding it. This will help build trust between you and your fish and make it more likely to come out in the open.
* Add a background to the tank. A background will help the fish feel less exposed and make it more likely to venture out.
