Is the moonlight gourami suitable for beginners?

Yes, it's rated as beginner-friendly. That said, adults grow to about 14-15cm, so it's important to provide a tank sized for their eventual growth.

Can it be kept with other fish?

It's generally calm-tempered, but it may eat any fish small enough to fit in its mouth. Choose tankmates of similar or larger size.

How can I tell males and females apart?

As males mature, their pelvic fins change color from orange to red, which makes it fairly easy to distinguish them from females.

What is the purpose of its long pelvic fins?

The unusually long, thread-like pelvic fins are thought to function as sensory organs that help the fish sense its surroundings. They're delicate, so care should be taken to avoid damaging them.

It's described as shy—what kind of environment suits it best?

A calm layout with plants or driftwood to hide in suits it well. It feels more secure with places to retreat to, rather than an overly open environment.

Moonlight Gourami

The moonlight gourami is a tropical fish prized for its shimmering silvery-white body and unusually long, thread-like pelvic fins that trail behind it as it swims. These fins act as sensory feelers, helping the fish explore its surroundings, and their graceful movement makes the fish stand out in any tank. Temperamentally calm but somewhat shy, it appreciates plenty of plants or décor to retreat into. Keep in mind it will eat smaller fish that fit in its mouth, so tankmates should be chosen with size in mind. As males mature, their pelvic fins turn from orange to red, making it easy to tell males and females apart. Rated beginner-friendly, this gourami is a good choice for newer hobbyists.

About Moonlight Gourami

The moonlight gourami features a silvery body and long thread-like pelvic fins. Calm and beginner-friendly, it grows to about 14-15cm.

7 things to know before welcoming a Moonlight Gourami

1Plan Tank Size for Adult Growth
Moonlight gouramis grow to about 14-15cm as adults, so plan for a tank that accommodates their full size even while they're still young. A cramped environment can cause stress.
2Provide Hiding Spots
Although calm, this fish is somewhat shy, so adding plants or driftwood for hiding spots helps it feel secure. Avoid overly open, exposed layouts.
3Choose Tankmates Carefully
This gourami may eat any fish small enough to fit in its mouth. When choosing tankmates, pick species of similar or larger size.
4Protect the Delicate Pelvic Fins
The long, thread-like pelvic fins are delicate and can be damaged by sharp décor or aggressive tankmates. Choose layout items and companions with this in mind.
5How to Tell Males from Females
Mature males develop pelvic fins that turn from orange to red, making it relatively easy to distinguish them from females. This is useful when keeping multiple fish or planning a pair.
6Labyrinth Organ and Water Surface Access
Gouramis breathe air using a labyrinth organ, so leave enough space at the top of the tank for them to reach the surface, and avoid sealing it completely with a lid.
7Prepare for Proper Acclimation
While considered hardy and beginner-friendly, this species is still sensitive to sudden changes in water quality or temperature. Take time to properly acclimate new fish when bringing them home.
