Ichthyologist
Ichthyology is the branch of zoology devoted to the study of fish, including bony fish ( Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha). According to FishBase, 33,400 species of fish had been described as of October 2016, with approximately 250 new species described each year. Etymology The word is derived from the Greek words ἰχθύς, ''ikhthus'', meaning "fish"; and λογία, ''logia'', meaning "to study". History The study of fish dates from the Upper Paleolithic Revolution (with the advent of "high culture"). The science of ichthyology was developed in several interconnecting epochs, each with various significant advancements. The study of fish receives its origins from humans' desire to feed, clothe, and equip themselves with useful implements. According to Michael Barton, a prominent ichthyologist and professor at Centre College, "the earliest ichthyologists were ''hunters and gatherers'' who had learned how to obtain the most usef ...

Green Neon Tetra
The green neon tetra (''Paracheirodon simulans'') is a freshwater fish of the family Characidae of order Characiformes. It is native to the upper Orinoco and Negro Rivers in South America.

Also, its body is slimmer than that of the neon tetra. It grows to a maximum overall length of about . Like the other ''Paracheirodon'' species, the green neon tetra is kept as an aquarium fish, but it is less commonly seen than either the neon tetra or the cardinal tetra. ''P. simulans'' is also sometimes called the blue or false neon. ''Hyphessobrycon simulans'' and ''Cheirodon simulans'' are obsolete synonyms. This fish loses its brilliant blue and red colors when lights are switched off, but regains them when lights are switched on again. The green neon tetra comes from ext ...
