The Indian Threadfin, sometimes known simply as the Threadfin, is best known for how thin it is, and its dorsal, anal, and pelvic fins which have long, thread-like filaments. Its shimmering, pale greenish-silver scales are reflective.

It requires a 125 gallon or larger aquarium with peaceful tank mates of similar size, particularly those that are not fin nippers.

The Indian Threadfin diet consists mainly of bits and pieces of meaty foods that fall through the water, and occasional live items.
