Gymnotus carapo (Banded Knifefish) — Seriously Fish
Gymnotus carapo Linnaeus This page was last edited on 13 Julyat Medium, minimum population doubling time 1. Also responds to vibratory stimuli water waves: With these, the fish can sense the tiniest of movements as the field around it is disturbed, and navigate in total darkness, useful skills when hunting prey or avoiding predators in the dark. Ctenobrycon and Curimata and plant matter Ref. Inhabits turbid slow moving or standing waters Ref.
Possible tankmates include large, robust cichlids such as Cichla or Geophagus sp. It also possesses electroreceptors, which allow the fish to receive electrical signals.
Small fish will be eaten, but it can be combined with other similarly-sized species in a big enough tank. Our results demonstrate significant, but not diagnostic, differences among specimens representing seven new subspecies: Males provide parental care in nests excavated for eggs and larvae Ref.
The genus Gymnotus has undergone considerable taxonomic revision in recent years, with over 20 new species being described sinceincluding several that were originally considered to be G. Gymnotidae Weakly electric fish Fish described in Like other Gymnotids, it produces a weak electric field using specially-adapted muscle tissue located towards the tail.
Here we assess the structure of phenotypic variation in G. Shows auditory abilities, responding best to a frequency of Hz, with an upper limit above Hz Ref.
Feed live and frozen foods such as bloodwormprawns, earthworms, tubifex etc. Gymnotoidei from Middle America, with a key to species of Gymnotus”. Uses its long anal fin for locomotion. Large stones and pieces of bogwoodtwisted roots, and live plants all look good.
Abstract The banded knife fish Gymnotus carapo is among the most widely distributed, broadly adapted eurytopicand phenotypically variable fish species in South America, with a geographic range of about 14 million km 2from the Llanos of Venezuela to the Pampas of northern Argentina. Found also in shallow edges of streams Ref. Tends to inhabit sluggish or still waters and seems to prefer turbid environments.

A very widespread species in both Central and South America. The strength and details of this pattern varies, both individually and depending on region. Dried foods are not usually accepted.
