Tank compatibility

A generally peaceful Pleco with other tank mates. Do not keep with too many other bottom-dwellers or Plecos if not enough hiding places are provided to avoid any aggression.


Will accept most foods including catfish and algae wafers, appreciates bogwood in the diet and will also take meaty foods such as brine shrimp and daphnia.

Feeding regime

Feed once or twice a day, may be more active when the lights are off.

Environment Specifics

Prefers a spacious and well filtered tank with hiding places, bogwood, rounded stones and caves provided.


A peaceful, mostly nocturnal, Pleco.


This Pleco has long branched bushy "bristles" when mature, mostly so on the males, which is unique in the Ancistrus family. The Medusa's bristles are long and thick. Its body is dark brown/black and slightly mottled, the belly is pale.
