My Aquarium Collection

A glimpse into my underwater world - where passion meets nature!

Underwater Ecosystem

My aquariums feature carefully selected species that demonstrate both beauty and natural evolutionary principles in action, from the efficient swimming patterns of tetras to the specialized adaptations of loaches.

I made this site because I want to share my passion for fish, and right now, I have a great big obsession with Kuhli Loaches. I've been collecting and observing the different species of Kuhli Loaches for a few years now, and I've learned a lot about them. They are wonderful creatures, and I'm proud to have them in my aquarium, and wish to show their beautiful and diverse behaviour to those interested.

All of the photos and videos are my own, and feature fish from my own aquariums. Feel free to use these photos and videos for your own content, but please give credit to me and my website.

Featured Species

Kuhli Loaches (Pangio Genus)

The fascinating world of Kuhli Loaches showcases incredible biodiversity within a single genus. These eel-like bottom dwellers demonstrate nature's evolutionary design at its finest, with each species adapted to specific ecological niches. Their burrowing behavior and nocturnal nature make them the perfect engineers of the aquarium substrate.

Kuhli Loach Varieties in My Collection

"Neon" Kuhli Loach

Pangio doriae

Distinguished by its unique iridescent coloring, slightly longer length, and cylindrical body cross-section. This species demonstrates excellent substrate burrowing capabilities. My personal favorite Kuhli Loach.

4-5 inches Green iridescence

Eel Kuhli Loach

Pangio anguillaris

The most eel-like of the group with an elongated body. Often confused with Pangio doriae, but lacks nasal barbels, and more mottled in coloration. The body cross-section of a mature Pangio anguillaris is much smaller than either Pangio doriae or Pangio kuhlii.

4-5 inches Golden brown

True Kuhli Loach

Pangio kuhlii

The classic Kuhli Loach with distinctive orange and black coloration. The most commonly kept variety, known for its social behavior. Displays the most variance in possible colorations within the species of all Kuhli Loaches.

3-4 inches Orange/black bands

Malaysian Kuhli Loach

Pangio malayana

Smaller and more delicate than other varieties. Has sparsely distributed circular (from above) spots, and lacks nasal barbels. Sometimes, but not often, this species has no dark spot/band over its eye, unlike other banded Pangio species.

2-2.5 inches Orange/black bands

Oblong Kuhli Loach

Pangio oblonga

The most hardy and robust of the commonly available Kuhli Loaches. Has the craziest zoomies out of all Kuhli Loaches. Whether it be a feeding, a water change, or any other activity in the tank, these stealthy squishies are bound to get excited.

3.5-4 inches Dark brown

Myers' Kuhli Loach

Pangio myersi

A rare and distinctive variety with unique patternin, with very strong contrast between adjacent colored bands. Has the largest maximum size and mass of all the Kuhli Loaches. Often described as "Giant Kuhli Loach".

4-5 inches Orange/black bands

PAN02

Unidentified Pangio Species

A mysterious and unidentified Pangio species, showcasing the ongoing discovery and classification challenges in ichthyology. Very small (even amongst other Dwarf Kuhli Loaches) and light brown in color. Has maximum girth that approaches that of Pangio anguillaris, but remains far shorter in length.

1.5-2 inches Unknown boi

Dwarf Kuhli Loach

Pangio cuneovirgata

Has unique and distinctive wedge-shaped stripes. Almost always labeled as "Dwarf Kuhli Loach", but is one of several types of dwarf kuhli loaches. Almost always has a dark band over the eye, like most other patterned Kuhli species. This species also often displays a dark purple coloration on the belly.

3-3.5 inches Wedge stripes

Borneo Kuhli Loach

Pangio alternans

Distinguished by its alternating band pattern and unique coloration. There are several similar species that are often confused as all being Pangio alternans, but all are actually other unclassified species. I would personally consider this species a "medium-sized" Kuhli Loach, with a maximum size that is intermediate between Pangio cuneovirgata and Pangio kuhlii.

3-3.5 inches Alternating bands
