As the name implies, this is a spiny fish, but it also possesses serrations on the scales. All members of this genus are spiny by nature, making them difficult to handle. There are probably about 12 species in the genus (the number is unclear, as some have not been described and are currently referred to only by their “L” numbers). Of the described species, P. leopardus (Leopard Plec), from the Rio Negro area in Brazil, is one of the few other Pseudacanthicus that are fairly regularly available.
