Morphology
This is a standard binomial scientific name formed by a genus + specific epithet, so the combined meaning (‘a particular species of freshwater fish’) follows directly from the constituents identified as a fish genus and a fish species. Taxonomic naming conventions are cross-linguistically regular, so a learner who knows the two parts and the genus/species conventions will understand it refers to that species of fish.
Etymology
Xyphophorus helleri may come from a name that means 'sword-bearer': the first part, Xyphophorus, points to the long, sword-like tail of the male, and the second part, helleri, is 'named after' the person who first found or described the fish. That's why the name fits this small freshwater fish often kept in aquariums.
