Product Overview

The Threadfin or Featherfin Rainbow is one of a few Rainbows in which the males have long threads extending from their dorsal and anal fins. Rainbows are known for their characteristic large eyes, black or silver band that runs through the middle scale rows, deeply forked mouth, and two dorsal fins.

This peaceful Rainbowfish is a schooling fish that does best in a well planted aquarium. Rainbows appreciate a gravel substrate and may intensify their colors against a dark colored gravel.

An egg layer, the Threadfin Rainbow spawns on large clumps of moss. The parents should be removed from the breeding tank before the eggs hatch, usually after seven or eight days. The fry should be fed very small live foods.

Although Threadfin Rainbows have large mouths, their throats tend to be narrow. With this in mind, foods should not be too large. Iriatherina wernerishould be fed an omnivore diet of small live foods and prepared foods.

    Ron was not happy with the quality of the Threadfin he had when I ordered. He gave me a choice of refund or waiting til he had more. Glad I waited...they made it in great shape and seem to have been stressed very little which is a wonder with these fish. They are all doing great And eating well. Ron even threw in one for free since I had to wait a while on weather to warm up. I never worry when I buy from Alpha Pro!
