Similarly, it is asked, is a Pleco a catfish?
Plecostomus, or Plecos, are a group of armored catfish that belong to the Loricariidae family. They are by far the most popular catfish amongst fish keepers and in total there are well over 150 species.
Beside above, do Plecos really clean your tank? Some species of pleco do in fact eat algae such as the bristlenose, but plecos are also infamous for their waste, being able to double of triple the total bio-load of an aquarium. No cleaner type fish will tidy up your aquarium better than you can, and all of them will add to the biological load on the tank.
do Plecos and catfish get along?
Reply from Admin Chris: It is said that it's fine to keep juvenile Plecos together in the same tank but having larger ones together is not a good idea because their aggression levels are higher. These aren't like tank setups for pet turtles or big species like that.
