The body of the Lookdown fish is unusual and slightly bent, and it has a distinctive “hump” on its forehead. They seem streamlined and sleek and are colored silver. Their dorsal fin extends the whole length of their back, and their tail fin is forked. Their huge eyes are high on the skull, giving them a peculiar upward-looking expression. They also have tiny mouths and pointed teeth. Because of the way they seem to be staring down, they are also known as lookdown fish. They can control their pigmentation to create a mirror-like body that reflects bright or low light, depending on the environment and what would best conceal them at the time.

Natural surroundings and behavior

They are often found in coastal waters, near the water’s surface, in bays, lagoons, and estuaries. As pelagic fish, they spend most of their life swimming in the open ocean instead of being submerged. They are often seen in groups called schools. Sandy bottoms and crystal-clear water are also known to appeal to them. They may be found in brackish and high-salt waters of all temperatures. Because their body structure makes them agile and unexpectedly swift, they escape artists when predators pursue them and are skilled at concealment.

Lookdown Fish Diet

Because it is a carnivore, the Lookdown fish should consume many types of meat, including brine shrimp, squid, krill, mysis shrimp, and small fish. Additionally, they could take flakes or pellets made for predatory fish. Since they have a reputation for being picky eaters, it could take some effort to locate a dish they will consume. Instead of one central feeding, giving them little, regular meals throughout the day is crucial. In addition to preserving the water’s purity, this will assist in avoiding overfeeding, which may have adverse health effects.

Additionally, mixing up their meals as often as possible is critical to provide a balanced diet and preventing boredom. Be aware that they should be fed in groups rather than individually since they are schooling fish. Doing so may encourage natural feeding habits and lessen rivalry amongst tankmates.

This species is incredibly resilient and may live very long when given ample swimming places in a big tank. Maintaining them in groups of four or more is best since they are shoaling fish. Even though they are calm fish, keep them away from tiny fish since they can devour them. Because they are enormous and need similar broad, spacious swimming areas, batfish, for instance, make fantastic buddies. They can also survive in water with various salinities, temperatures, and less-than-ideal circumstances. Please provide them with the cleanest aquarium water you can, nevertheless, for long-term success.

Between 24 and 27 °C (75 and 80 °F) is the ideal temperature to maintain a Lookdown fish in an aquarium. This temperature range closely resembles the fish’s native home, which is the warm seas of the western Atlantic Ocean.

The aquarium has to be kept at a consistent temperature since unexpected temperature fluctuations may stress fish and harm their health. Using a heater and a reliable aquarium thermometer, you can keep your Lookdown fish in the proper temperature range. Because Lookdown fish are sensitive to temperature variations, it’s also critical to remember that the temperature in the tank must remain constant. May accomplish this by employing many heaters and distributing them around the tank in various locations.


The lookdown has the potential to become a popular aquarium fish because of its peculiar form, colour, and activity. This fascinating species would complement many pelagic or sand flat exhibitions. It is relatively undemanding in its care whenever it is given an adequate living area. The expanding understanding of its ecology and the current availability of tank-raised individuals provide home aquarists with a rising chance of success with the species.
