In Aquanswers, Momchil shares knowledge about freshwater and saltwater home aquariums with the people from his community. This fish breathes air so that’s normal behavior for larger, more lethargic specimens. They have relatively well developed eyes and pectoral fins compared to saltwater eels that they use to navigate and maneuver through river bottoms and shallow water. I’ve put together a list to help with all of that.

Though it might not sound like the most nutritious of diets, specimens of the common G. broussonnetii have been recorded at nearly 2 feet in length (though the common size of this fish is usually more like 10 inches). The identification of this miniature eel-loach highlights the huge numbers of species on our planet still to discover. Because so little is known about its distribution, its conservation status is unknown. The only way to tell apart a zig-zag eel from its tire track cousin is the pattern and its pronunciation. If you do plan to look after more than one, then you have a “window” of 3 to 4 months. It occurs in swamps of West Africa, from whence it emerges at night to feed upon invertebrates.
