Description

To protect our animals and to ensure they get to our customers healthy, we will only ship orders with Nano Fish via UPS Next Day Air.

The Threadfin Rainbowfish (Iriatherina werneri) is a small, peaceful, and visually stunning freshwater fish prized by aquarists for its unique, delicate finnage and lively, dancing movements. Native to slow-moving waters in northern Australia and New Guinea, these fish are an excellent addition to a well-established community tank.

 The Threadfin Rainbowfish gets its name from the males' exceptionally long, thread-like dorsal and anal fins. Their bodies are typically a light, translucent color with hints of yellow, blue, and green. Males are the most vibrant, displaying their incredible finnage and color to attract females. Females have a similar body color but lack the elongated fins.

Threadfin Rainbowfish are pretty easy to care as long as they are introduced to a mature, cycled tank. They can acclimate to a wide range of parameters.  The following are our water parameters we keep them at:

Our Tank Water Parameters

PH: 7.2 to 7.5
GH: 7 to 8
KH: 3 to 4
TDS: 180 to 250
Temp: 75F to 80F

We feed them a mix of live baby brine shrimp, frozen daphnia and high-quality flake food.

New favorite

I was very iffy ordering them but only because I was worried about their threads and my other fish nibbling on them but these absolutely GORGEOUS fish stand their ground. I can't stop staring at them. Kicking myself for only ordering 2. They are definitely my new favorite and obsession lmao

The fish was healthy. It was a little on the small side but I like that way so That I can enjoy them a little longer.

Wonderful little fish

All the fish were alive and acclimated well to my tank. I have an established school of adults, and it took me a minute to remember the new fish are juveniles as the look so different. The juvies have taken up with the main school and are thriving. Looking forward to when they grow up and get the wonderful adult coloration and fins.

Beautiful

I ordered 4 of these for my shrimp tank. Unfortunately they all passed away within 2 days of receiving them despite looking great, exhibiting normal behaviors and eating well. Classic delayed shipping damage, which is not a reflection of Shrimpy Business.
