olomina -- what is the definition?
From a book I am reading the word "olomina" is used a lot in one chapter. Here is one bit of context:
"No son pescados. Son peces nadando en una pecera. Se llaman olominas."
I know they are some kind of tropical fish (I want to think they are "guppies") Ok "olomina" is not in my dictionary; not on this site, not on WR, but I found it on RAE.
From RAE
f. C. Rica, El Salv. y Hond. Nombre genérico de varias especies de peces pequeños, que habitan en aguas dulces o salobres de Centroamérica. Son comestibles curados y salados.
So are "olominas" guppies" or a generic tropical fish. Nothing serious here I am just curious.

Guppy is a different fish (Poecilia reticulata)

<<many small livebearers both in and out of the genera Brachyrhaphis are known by the common name Olomina. This word is a bit difficult to translate (it is Spanish in origin) but probably means something like the English word "minnow," describing a small fish that's identity is deemed unimportant. It is also the name used for guppy. That they are all enclosed in the same common name is understandable considering their relative uselessness in commercial terms. They are too small to be used as a food fish, have yet to become popular in the aquarium trade, and all have a similar body shape and coloration.>>

I found this on petfish.net
Common Name: Olomina Latin Name: Brachyrhaphis holdridgei It looks very similar to Brachyrhaphis roseni (and goes by the same common name, Olomina),
so it seems the common name is the same in english.
Guppies
