   One of the hardiest and most enduring of all catfishes, the Pleco or Plecostomus is the most common catfish used for getting rid of problem algae in the aquarium!

   The Sailfin Pleco or Plecostomus are nocturnal so it is best to feed them in the evening just before turning out the lights. A word of caution, they have been known to remove slime from laterally flattened fish like discus and angelfish when they are sleeping! Even though they are herbivores they can get quite large and can become too big for small aquariums.

   Keep some wood in the tank since rasping algae from the wood provides a perfect place for more algae to grow maintaining a constant food source for this fish. Also, the cellulose in wood is necessary for their digestive process.

   Pleco or Plecostomus make very good community fish as they are peaceful with other tankmates. The only exception to this is they can get aggressive and territorial towards other plecos if they were not raised together.

   There are many species (over 100 species) sold under the name "Pleco" and the main differences between the species seems to be in their varying color patterns. The Hypostomus genus is more frequently sold in pet stores, but the Sailfin Plecostomus is sometimes available as well.

Whats in a name?            gibbiceps comes from the Latin gibbus—hump and Greek cep—head

Geographic Distribution
Glyptoperichthys gibbiceps
Data provided by FishBase.org
  • Kingdom: Animalia
  • Phylum: Chordata
  • Class: Actinopterygii
  • Order: Siluriformes
  • Family: Loricariidae

Habitat: Distribution / Background

   The Pleco or Plecostomus are found in river systems in most parts of South America.

  • Scientific Name: Glyptoperichthys gibbiceps
  • Social Grouping: Groups - Can be kept as single specimens in the home aquarium. If the fish are not raised together and the aquarium is not large enough, territorial disputes may arise between individuals.
  • IUCN Red List: NE - Not Evaluated or not listed

Description

All Plecostomus are very popular because of their peaceful nature and ability to help keep your aquarium free of algae. The Sailfin Plecostomus is no exception. They are herbivorous and will pose no threat to smaller peaceful tank mates. Plecos have an elongated, dark brown body with a large head. The body is covered in bony plates except the belly which is flat. Plecos have small eyes that are set high on the head. The Sailfin pleco has a beautiful dorsal fin the can be several inches high and resembles the dorsal fin of the marine Sailfish.

  • Maximum Size: 20.0 inches (50.80 cm) - This fish is often sold to aquarists coming into fish stores complaining of high algae, who will enter and leave the store without realizing how large the adult size of the fish they have just purchased. Additionally, it is often falsely reported that this fish is a suitable algae eater for goldfish bowls which is not the case for this tropical fish.

Fish Keeping Difficulty

  • Aquarium Hardiness: Very Hardy
  • Aquarist Experience Level: Beginner

Foods and Feeding

   Since they are herbivorous the Pleco or Plecostomus will eat undesirable algae. They will not harm plants, but make sure the aquarium is well seasoned and do feed a supplemental sinking algae pellet to make sure they don't starve. Because they are super algae eaters, they must have their veggies! (Note: they have not been observed to eat blue algae.)

  • Diet Type: Herbivore
  • Flake Food: No
  • Tablet Pellet: Yes
  • Vegetable Food: All of Diet - Feed algae wafers or sinking pellets to ensure they get enough to eat, especially in aquariums with little or no algae.
  • Feeding Frequency: Weekly - The Leopard Pleco will happily subsist on the algae growth in the tank provided it is plentiful enough. The aquarist keeping a Pleco for these purposes should only feed their specimen(s) when algae levels become too low.

Aquarium Care

  • Water Changes: Bi-weekly

Aquarium Setup

The aquarium should have plenty of wood for the fish to 'chew'. Not only do they rasp off algae, but the wood may provide a necessary digestive aid.

  • Minimum Tank Size: 100 gal (379 L)
  • Substrate Type: Any
  • Lighting Needs: Moderate - normal lighting
  • Temperature: 73.0 - 86.0° F (22.8 - 30.0° C)
  • Range ph: 6.5-8.0
  • Hardness Range: 4 - 18 dGH
  • Brackish: No
  • Water Movement: Moderate
  • Water Region: All

Social Behaviors

   They are a good community fish, they are not aggressive and because they are herbivorous, smaller fish are in no danger of being eaten.

  • Venomous: No
  • Temperament: Peaceful - Although peaceful by nature, specimens will occasionally develop a taste for the slime coating of their tankmates. Large, slow moving, laterally compressed fish such as Discus and Angelfish are in particular danger in this regard. Furthermore, Leopard Plecos who did not grow up together may be hostile towards one another if suddenly placed in shared quarters.
  • Compatible with:
    • Same species - conspecifics: Yes
    • Peaceful fish (): Safe
    • Semi-Aggressive: (): Monitor
    • Aggressive: (): Monitor - Many semi-aggressive and aggressive fish will not bother plecostomus catfish.
    • Slow Swimmers & Eaters: (): Safe
    • Shrimps, Crabs, Snails: Safe - not aggressive
    • Plants: Monitor - Adult Sailfin Plecostomus will eat many plants.

Sex: Sexual differences

   Not known.

Breeding / Reproduction

   This fish has not successfully been bred in aquariums.

  • Ease of Propagation: Difficult - A precise method of breeding has yet to be defined although there are various methods that appear successful. The condition of the fish seems critical to breeding. Since Leopard Plecos are so large there are certainly practicality evaluations that need to be made before breeding this fish.

Fish Diseases

 Plecos are very hardy fish, but are subject to the same diseases as other tropical fish. One of the most common freshwater fish ailments is ich. For information about freshwater fish diseases and illnesses, see: Aquarium Fish Diseases and Treatments.

Availability

   The Pleco or Plecostomus is readily available.

I have a two and a half inch long fin bristle nose. When I got him, he had awesum long fins. After having him for two mounths his fins are not as nice as they were. He is in realy good conditions and he has never been nibbled on. Can you please tell me what this is?

    I included the article on Fish Disease and Treatment. It might be Fin & Tail rot which is a bacteial infection. He could have had it when you brought him home. He could have hurt himself somehow in the tank and it caused a bacterial infection. Another fish could have nipped him. It happens. Anyway, look at the article and find the symptoms and check out that disease and just look at symptoms in general. The recomended treatment is there.

    It would be highly likely to be a simple common plecostomus.

NEED SOME ADVICE! I have have had 3 common plecos all at different times, however I can't seem to keep them for more than 3 weeks! I have a well established community tank of which I spoil all my fish rotten! Each pleco I have had seems to be happy and doing well and then I come home to find it dead.... have I just been unlucky with my pleco picking or am I doing something wrong? I thought these were hardy fish.....

    Do you have smokers in the home that may be reaching into your fish tank? I use to smoke and my two boys use to put cigarette butts into my fish tank and it would kill all the fish. Some sooner than others. They did this on purpose. I didn't find out until many years later.

    Don't expect your pleco to survive on algae or leftovers alone! Be sure to feed him. They love the sinking algae wafers. Zucchini, green beans and broccoli are all avidly consumed by any of the plecos we own. Microwave the veggies a little to soften them, cool and drop into tank late in the day. Remove any uneaten bits the next day. We have 7 different tanks, all with their own species of pleco: common, tiger, clown and some only known by their "L" number. We love these animals! Good luck.
