    Batrachops spp.


    Pike cichlids Pike cichlids (Crenicichla spp. and Batrachops spp.) can sometimes be confused with snakeheads, but they have short anal fins and spines are present in both the dorsal and anal fins (Howells, 2004).
    Channa spp.


    According to Howells (2002), all Channa spp. are elongate and torpedo-shaped with long dorsal and anal fins. They have rounded caudal fins. Coloration varies dramatically between species and ages. It may range from bright reds to natural tans, browns, and grays, and can include patterns of stripes or blotches. Some, like C. marulius, have an ocellus (eyespot) at the base of their caudal fin; others do not.

    Amia calva


    Helias (2002) indicates that C. marulius is an air-breathing fish similar in appearance and behavior to the native bowfin (or mudfish). However, C. marulius has the trademark black spot rimmed with orange near the base of the tail fin.
