Corydoras eques, the horseman's cory catfish or true eques cory, [1] [2] is a tropical freshwater fish belonging to the subfamily Corydoradinae of the family Callichthyidae. It was first described by Austrian zoologist Franz Steindachner. [3] It is native to the Brazilian Amazon basin. [4] The name eques means knight in Latin. [5]
Corydoras is a genus of freshwater catfish in the family Callichthyidae and subfamily Corydoradinae.The species usually have more restricted areas of endemism than other callichthyids, but the area of distribution of the entire genus almost equals the area of distribution of the family, except for Panama where Corydoras is not present.

Apomixis (self-cloning), where seeds are produced asexually and the new plant is genetically identical to its parent; The mode of reproduction of a crop determines its genetic composition, which, in turn, is the deciding factor to develop suitable breeding and selection methods. Knowledge of mode of reproduction is also essential for its ...
They are often kept at a pH of between 6.5 and 7.0. They are schooling fish that are usually kept in groups of at least four and will also behave much more naturally in larger groups (10 or more). Unlike the larger more common Corydoras, they often swim in shoals around the mid water and lower regions of the tank.

Most of these species are in the genus Corydoras, the largest catfish genus. [ 3 ] The subfamily Corydoradinae includes about 90% of the species in the family Callichthyidae and is one of the most diverse siluriform assemblages in the Neotropics , with about 170 valid species. [ 5 ]

Mutation breeding, sometimes referred to as "variation breeding", is the process of exposing seeds to chemicals, radiation, or enzymes [1] [2] in order to generate mutants with desirable traits to be bred with other cultivars. Plants created using mutagenesis are sometimes called mutagenic plants or mutagenic seeds.
