    Serrasalmus Manueli Info

    Serrasalmus Manueli

    Considered by aquarists as a delicate species in need of good water quality and oxygenation. Recommend keeping as solitary species in home aquarium. This species commands high prices in the hobby. Certainly not a fish for beginners. Expect mortality if not properly cared for. Aquarium size would likely be in the 100 gallon minimum or largest aquarium you can afford to buy. Frequent water changes (3x per week at 10-15%) suggested.
    The map shown herein are approximate range of certain species. It does not show the complete range. This type of pirambeba grows huge, some exceeding 33 cm SL (Machado-Allison and Fink 1996). David (Schleser) in his Piranhas A Complete Pet Owners Manual states that "Manuel's piranha can grow to at least two feet (61 cm) in length." These fish are being captured in Venezuela and in particularly the Rio Xingu. Without a doubt a fish best left for the largest of aquariums. It has the distinctive dark "V" caudal fin and hyaline edging. This and S. gouldingi juveniles are very close in appearance. Below is the citation that pertains to this particular species and a translation to be used for educational purposes only. The large shoulder blotch is distinctive of this species. Some forms in the lower Amazon are grow larger. Usually found with S. rhombeus.

    WATER
    These are deep water fish and need good slow to medium aeration. They are normally found in river channels, however they can also be found in Creeks, Lagoon, and Sand banks. The fish inhabits *black water regions (pH 4.-5.8 with low conductivity) according to Winemiller, et al. 1997. The area also undergoes a period of a dry season from October - March. The rainy season runs from April - September.
    According to fishermen, as told to Edouard Paiva, in that region of the Rio Cinaruco in Venezuela you find many Serrasalmus manueli, the water is detailed here:
    - The PH values goes from 4,6 to 6. The visibility is very good up to 2 meters deep and it has very few nutrients and minerals dissolved.
    - The water is clear or transparent.
    - It is a deep river the fishermen say that it is normally from 15 to 20 meters deep.
    - The water temperature goes from 25 to 30 centigrade.
    - The river has a very low current, calm water.
    WILD CAUGHT
    Semaprochilodus kneri, Hydrolycus armatus and other common fish species are found with S. manueli. Edouard Paiva sent pictures of a big Serrasalmus manueli captured in Rio Cinaruco in Apure State in Venezuela. It weighted 2.2 kilograms 4.84 pounds and its total length is 41 centimeters (16 inches). According to the information of the fishermen in that river it can grow a lot more than that up to 52 centimeters long and more than 3 kilograms.
    Body condition and Fat stores increase significantly during this falling -water period (Jepsen et a. 1997). During the low-water season progresses, virtually all Cichla have empty stomachs, and gonadal maturation occurs in preparation for spawning just prior to the beginning of the floods (Japsen et al. 1997, Jepsen and Winemiler unpublished data). Likely, S. manueli may also fall into this category of physical changes during that period.
    PLANTS
    Eicchornia spp. Paspalum repens and other Graminaceae.
    DIET
    The species is known to frequent the rain forest where its diet includes seeds and fruit. It is found in the low Llanos of Venezuela (Machado-Allison and Fink, 1996 and Schleser 1997). Semaprochilodus species may be one of the foods of S. manueli, but little study has been done to confirm it. Likely, S. manueli feeds off the fins and flesh parts.
    MAXIMUM SIZE
    43.5 cm TL (probably grows larger).
    SCIENCE
    WILLIAM L. FINK: Pygocentrus manueli, Fernández-Yépez and Ramirez (1967), described as a Pygocentrus from the Rio Paraguaza of Venezuela. This species is a Serrasalmus and is discussed by Fink and A. Machado-Allison (unpubl..) and Fink and Machado-Allison (1992).
