STRIPED BULLDOG PLECO/ STRIPED RUBBER NOSE PLECO (Chaetostoma formosae) is formerly known as L187b. Also, L444 was found to be genetically identical, so that is now referred to as C. formosae as well.

  • Sultan Pleco
  • Zebra Pleco

I have mentioned in the past that not all plecos have the same requirements, although usually when I say that I am referring to food requirements.

The Striped Rubbernose Pleco has a different need you need to meet if you want to keep it alive; rapidly moving highly oxygenated water.

Tank And Nature

These little catfish are ideal candidates for a hillstream tank. But if you are going to keep it in a hillstream tank with the usual types of rock dwelling fish such as hillstream or Garra loaches, be sure to have lots decor that creates a broken line of sight, and builds lots of caves. The same holds true if you plan to have more than one rubber nose. They can be very territorial with each other.

Caves are a good idea so each fish will need a cave or crevice to claim as its own to retreat into. If you are using a gravel substrate, be sure to anchor the stones or cement them together with aquarium-safe silicon because, if the rubber nose pleco does not like the caves provided, he or she will attempt to excavate their own underneath the stones. A single specimen could be kept in a 20-gallon tank, but a 30 (115 liter) is better when housing more than one.
Origin: Columbia
Size: 4in/ 10cm
Temperature: 20-24°C/ 68-75°F


Likes to feed on the biofilm and algae growing on the stones, walls and other decorations in the aquarium. They reluctantly eat vegetables but love and need regular feedings of frozen bloodworms or other invertebrates.


Whenever keeping these fish, you need to have an oversized filter on the tank creating a steady flow as well as an additional powerhead and added oxygen. Rocks and driftwood can be added, but it is hard to grow plants in the strong currents these fish prefer. The substrate can be entirely stone of gravel of various sizes. Employ bright lighting to encourage the growth of algae and biofilm for these fish to graze on.


These fish may spawn in caves in well-established tanks, but setting up a separate spawning tank for them to breed it has so far produced no results. Spawnings in captivity have all been accidental.
