The firefish does exceptionally well in almost any type of marine aquarium. This fish is almost always available at local fish stores at very reasonable prices. Groups of firefish can be kept in larger tanks as long as there are plenty of holes in the rockwork for them to hide in and claim as their own territory. Single fish make perfect inhabitants for the very popular nano reef tanks which are usually between 2 and 5 gallons in capacity. When kept in these small tanks with some live rock and soft corals, firefish make a very effective display.
Because it is a very timid fish, the firefish should not be kept with other fish that will compete with it for food. This fish typically hangs in the water column, waiting for plankton to drift by for it to capture. Feed this fish finely chopped meat foods such as shrimp, Mysis shrimp or frozen prepared carnivore diets. The best thing to do is to introduce a tiny amount into the water column a few times a day, always making sure that all of the food is eaten before feeding any more. With its long thin dorsal fin flashing all the time, the firefish makes a very interesting and attractive addition to any tank.
