Naso lopezi

Naso lopezi: the streamlined naso, discreet but essential for tank balance

The Naso lopezi, also known as the streamlined naso, is a large surgeonfish belonging to the Acanthuridae family. This species, native to the western and central Pacific, is distinguished by its elongated, slender, and slightly curved body, perfectly adapted for swimming in areas with moderate to strong currents.

Less colorful than its cousins like Naso elegans or Naso lituratus, the Naso lopezi is nonetheless remarkable for its discreet silvery gray hue and its very fluid silhouette. It possesses two caudal scalpels like all members of its family but does not display a prominent frontal hump. It is appreciated for its calm behavior, robustness, and ability to maintain a clean aquarium thanks to its algae-eating diet.

A peaceful behavior suited for community tanks

The naso lopezi is a peaceful fish that easily cohabits with other marine species, especially non-aggressive and size-compatible fish. It can be kept alone or in groups, depending on the tank's volume. Thanks to its gentle temperament and relative discretion, it is perfectly suited for a community reef aquarium.

It spends most of its time swimming in open water, exploring rocks and the decor in search of plant material to consume. It also enjoys calm areas where it can rest or position itself in moderate currents.

Maintenance conditions in a marine aquarium

The Naso lopezi requires a minimum tank volume of 800 liters. It needs large swimming spaces, strong water movement, and a well-oxygenated and stable environment. The aquarium should include open areas and a rocky decor rich in microalgae.

Sufficient water height and good circulation are necessary to replicate its natural conditions. Like all large swimmers, it requires a stable and mature system, well-maintained.

Herbivorous diet based on algae

The streamlined naso is a strictly herbivorous grazer that primarily feeds on natural algae. In an aquarium, it should be provided with:

• Nori algae several times a week, fixed on a clip or magnetic holder.
• Vegetable pellets rich in fiber and spirulina.
• Occasional supplements of mysis or brine shrimp, without replacing the plant matter.

A well-distributed diet rich in plant matter ensures good metabolism, regular growth, and stable behavior. It is important not to neglect meal frequency, especially for young individuals.

An equilibrating fish for experienced aquarists

The Naso lopezi is a useful, peaceful, and robust fish, perfect for large reef aquariums. Thanks to its calm behavior and constant grazing activity, it effectively contributes to the cleanliness and biological balance of the tank.

For aquarists with sufficient volume who wish to introduce a discreet but functional naso, the Naso lopezi surgeonfish is an ideal species, as aesthetic as it is effective in a well-structured decor.
