Lookdown (Selene vomer)
Lookdowns are extremely laterally compressed fish with long snouts and small mouths. The fish are shiny and silver in color. The second ray on both its anal and dorsal fins is many times longer than the surrounding rays. The combination of these elements gives the Lookdown a distinct and unique appearance. For this reason, Lookdowns (especially small sized lookdowns) are often sought after for large premium aquariums.
Lookdowns are a carnivorous fish, preying on small fish, mollusks, and crustaceans. They naturally form large schools in coastal areas but will break off into smaller groups or pairs on occasion.
Lookdowns have been spotted as far north as Canada and as far south as Uruguay, but they tend to follow warm currents.
Usually ignores corals but will eat fishes and other invertebrates. Also grows large, whose output of dissolved wastes may be problematic to the maintenance of pristine water quality.
Proaquatix specimens have been weaned to take aquarium pellets and flakes. Freshly frozen invertebrates such as ocean plankton, Mysis shrimp, brine shrimp, and chopped squid will be readily accepted.
