Comments: Though social, this species needs its space. A species tank with roughly 20 gallons per fish is sufficient as they maintain a relatively small size. Unassuming and timid, they are easily spooked by larger, more rambunctious fish. Spiny Eels will sometimes bury themselves in the substrate with only their heads sticking out, waiting to ambush smaller fish. Thus, a fine grained gravel or sand substrate is preferred.
