I recently acquired a few wildcaught specimens from Brasil labelled as "A. bita"...In the retail store, that particular group of fish included A. bita and A. aggie (as usual). To my surprise, there are also many A. mendezi "Long strips" (A220)!! It's the first time I found both wildcaught A. bita and A. mendezi together!! The question is: do these two species co-exist in some region of the Rio Negro? What I know is mendezi's distribution is mainly in the upper and middle parts of the Rio Negro while A. bita (Brasil) seems to distribute in the much lower part of the Rio Negro, and in regions around the export centre Manaus (also in another stream with places/rivers such as Manacapuru, Coari, Tefe, etc). In addition, A. mendezi "Long strips" should reside mainly in upper and eastern part of the Rio Negro which is even much farther away from the reported locality of A. bita... Any comments on it?
