Short Description

It should be noted that the Adonis Plec grows large when nature so a very large aquarium with a large footprint will be required to give this fish ample swimming room, the tank length should be at least three times its body and the width twice its body length. Like most plecs they do require well oxygenated water and it should be kept to the highest quality with a suitable filtration system and plenty of water changes. They also require dimmed lighting, floating plants will help with this, they also like to burrow in the substrate so live aquarium plants are not a good choice for décor, rocks or driftwood will provide ample hiding places to make them feel secure.

Don’t be fooled by the peaceful nature of juvenile specimens, as they mature they will become highly territorial, especially male specimens. Only keep these as a single specimen in any aquarium or behavioural issues will develop as they squabble for their own territory, it is also advised not to add any other bottom dwelling fish with these.


Adonis pleco accept all types of fish food. Bloodworms, larvae, granules, tablets, beef heart, etc.


See, please.


They breed after they are 8 years old but there are no reported cases of the Adonis plec breeding in the aquarium. Like their close relatives, it is believed that they dig caves in the river banks to act as nests with the male assuming the parental care, driving the female away after spawning.
