Disclaimer:

The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Moenkhausia sanctaefilomenae (Steindachner, 1907)

Common name: redeye tetra

Taxonomy: available through www.itis.govITIS logo

Identification: The genus is in need of systematic revision. Géry (1977) provided a key and photographs. Color photographs appeared in Axelrod et al. (1985) and Sakurai et al. (1993). This species closely resembles the glass tetra Moenkhausia oligolepis in body form and coloration but has fewer lateral line scales.

Size: 7 cm SL.

Native Range: Tropical America, in Paranaíba, São Francisco, upper Parana, Paraguay and Uruguay River basins (Géry 1977, Lima et al. 2003).

Means of Introduction: These fish were either released or escaped from a fish farm, or were aquarium releases.

Status: Failed in Florida.

Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.

Remarks: This is species is common in the aquarium trade. Voucher specimens: Florida (UF 98917) but listed as Tetragonopterus sanctaefilomenae.
