Cercopagis pengoi (fishhook flea), a relatively small species, is a consumer of other small zooplankton nearly as large as itself, including small cladocerans (e.g., Bosmina longirostris, early instars of Daphnia spp.), as well as nauplii and early copepodite stages of copepods.

Yearling alewife directly compete with Cercopagis pengoi because they are planktivorous but cannot consume C. pengoi due to its caudal appendage.

The fishhook waterflea (Cercopagis pengoi) is likely to be a competitor of Leptodora kindti because of similar food preferences, similar life histories, and similar habitat preferences; both are found in the epilimnion.

Because of its large feeding appendages, it is possible that Cercopagis pengoi is a more effective predator of zooplankton of a broader range in size and escape abilities than Leptodora kindti.
