The Lookdown, sometimes known as the Threadfin Lookdown, is best known for how thin it is, and its bright, shimmering blueish-silver scales which are highly reflective.

A 125 gallon or larger aquarium with peaceful tank mates, particularly those that are not fin nippers, is necessary.

The diet of the Lookdown consists of meaty foods and occasional live items.

Jacks are members of the family Carangidae which includes 32 genera and 140 species. They are found in tropical and subtropical waters in the Atlantic, Indian, and Pacific Oceans, and may be in schools, small groups, or pairs. Jacks are laterally compressed and often silver in color. They are fast swimming carnivorous fish which, in the wild, feed most successfully at dawn and dusk, when their superior vision gives them an advantage over their prey. In the aquarium environment they need a large amount of swimming room and a diet which should include meaty foods and occasional live items.
