Uses its long anal fin for locomotion. This map was computer-generated and has not yet been reviewed. Inhabits turbid slow moving or standing waters Ref. Gymnotoidei from Middle America, with a key to species of Gymnotus”.
Freshwater; tymnotus pH range: 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. Feed live and frozen foods such as bloodwormprawns, earthworms, tubifex etc. Dried foods are not usually accepted.
Entered by Torres, Armi G. It also possesses electroreceptors, which allow the fish to receive electrical signals.
There are also some morphometric variations depending on location. Males provide parental care in nests excavated for eggs and larvae Ref. Tends gynotus inhabit sluggish or still waters and seems to prefer turbid environments. Here we assess the structure of phenotypic variation in G. Articles with ‘species’ microformats. Central and South America: Moderate vulnerability 37 of You must be logged in to post a comment.
Small fish will be eaten, but it can be combined with other similarly-sized species in a big enough tank. Also responds to vibratory stimuli water waves: Native range All suitable habitat.
Relationship between EOD pattern and agonistic behavior in this species has been demonstrated Refs. 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.
Like other Gymnotids, it produces a weak electric field using specially-adapted muscle tissue located towards the tail.
The male sits on a depression with its anal fin expanded horizontally guarding a cluster of larvae. Our results demonstrate significant, but not diagnostic, differences among specimens representing seven new subspecies: This allows the fish to survive in polluted or hypoxic oxygen-deficient environments, and also comes in useful when waters recede at the end of the wet season if the fish becomes stranded, for example.
