Plecostomus

aka Pleco, Sucker Fish, Sucker Mouth, Catfish, Algae Eaters

Life span 
10-15 yr


Origin 
South America


Size 
At least 18inches depending on variety.


Temps 
70-82


Temperament
Typically these nocturnal fish have a peaceful solitary nature. However, they can be aggressive toward their own species.


Compatible
Many due their usually peaceful nature.


Tank Setup
Adults can grow quite large so depending on the type the minimum size tank would be 55 gallons. Hiding places, plants, and rocks should be provided.  


Diet
These bottom feeders are usually herbivores. There are some that require live, dried, and freeze dried and meaty based foods in their diets. They get their algae off of the glass and other surfaces in the tank. Plecos also enjoy: lettuce, zucchini, spinach, peas (smashed and placed on a rock like paste.)

Older Plecos eat algae less often. They’ll need it supplemented in their diet. This can be done with algae wafers that sink to the tank’s floor. Sinking shrimp pellets are also another favorite.

For best results it’s suggested that you feed after the lights have been turned off for the day. This helps prevent other fish from stealing your Pleco’s food.

Most of the armored catfish available are commonly referred to as Plecostomus even though they belong to other catfish species. Most will grow to a length of 10 inches.


Sexing
No visible difference between the genders.


Breeding
They can be difficult to breed in home aquariums. In fact one site even stated that there’s no reports of them breeding in captivity. In their natural habitats breeding is done in pits they’ve dug into the substrate. Once the eggs have been laid and fertilized they guard them until they’re hatched. Once hatched the young fry feed off the body mucus of their parents.

Most Plecos that are sold in pet stores are from eggs that were collected from riverbanks. After they are collected they’re hatched and raised on fish farms.
