- Plecos are a type of catfish.
- When we refer to plecos, we refer to the 138 species of fish that come under the genus Hypostomus.
- The plecos’ skin may look slimy, but its texture is like that of a rocky armour.
- Plecos are gentle with most fishes except their own species, who they can be very aggressive towards.
- Plecos never reproduce in captivity, but females can lay up to 300 eggs in the wild!
Veteran aquarium keepers never write or say aloud the plecos’ full name “plecostomus” because of an old superstition that says “speaking or writing the name will cause the fish to die”.
