    Topic Serrasalmus Compressus

    Post by ANDONI on Mon Jan 25 2010, 08:28










    Scientific name:

    Serrasalmus Compressus




    Apparently restricted to the Rio Madiera and its tributaries. Likewise
    is considered rare and collected with great effort. (Fink et al.,
    2001).





    Both S. Compressus and S. Altuvei look similar in body shape and
    color pattern, but the measurements for each separates them though it
    is subtle. S. Compressus is more concave in profile in the supra orbital
    region (back area) and more convex posterior to the supraocciptial
    spine (just before the dorsal spine) than S. Altuvei. S. Compressus has
    a more robust snout laterally than S. Altuvei. The ventral profile of
    the belly (side profile of belly) of many specimens of S. Compressus
    ventrally protrudes (sticks out more) to a greater extent anterior
    than S. Altuvei. All these features are more pronounced in juveniles
    than adults. (Fink et al., 2001).



    Color of Life

    Variable, Usually bright silver with red eyes often mistaken for S.
    Rhombeus and S. Altuvei when juvenile. Locality means everything to
    have a positive ID on this species.



    Reference to identify this fish

    · Red(dish) eyes

    · Pattern comprises of bars instead spots

    · Concave head shape



    Maximum Size

    Approx. 22 cm. (9") TL.

    Specimen over 18 cm. (7") TL are rare in captivity.



    Sexing

    Not sexually dimorphic: males and females look similar.

    Care:

    Minimum tank size

    50 to 100 gallons

    Tank Requirements

    Plants, drift wood or rocks provide hiding places, the tank lights should be dimmed.

    Heavy filtration required to deal with the large amounts of waste
    this fish produces. A power-head can be added to provide currents.

    Dangerous to hands and other extremities. Care is required in handling.



    Water temperature

    24-29 degrees Celsius (76-84 degrees Fahrenheit).



    Water chemistry

    pH should be between 6.0 - 8.0, ideal is slightly acidic to neutral water: pH 6.5 - 7.2

    Soft water is preferred.



    Compatible Species

    None: being a parasitic fin-nipper and very aggressive towards other fish, the Compressus Piranha should be kept alone.



    Breeding

    No captive breeding have been reported as of yet.



    Diet

    Fish (whole, fillet or feeders ), shrimp, cockles, mussels, squid, insects, earth worms, pellets.

    Food items such as poultry, mammal meat and organ meat should be fed
    sparingly: once or twice a month at most. Meat needs to be unseasoned
    and trimmed of any fat.

    On rare occasions this species accepts vegetables, nuts seeds or fruit as well.
