Aquaculture Species Identification Quiz

Corydoras panda is named after its black-and-white facial markings. Scientific classification places it within armored catfish. Other options represent tetras, bettas, or predatory catfish, which differ significantly in fin structure, scale type, and habitat preference.

Hypostomus plecostomus is identified by its ventral suckermouth adapted for algae grazing. The suction mechanism and bony plates separate it from scaled fish like goldfish or cichlids. Taxonomy is based on skeletal structure and feeding adaptation.

African cichlids exhibit mouthbrooding, a reproductive strategy where eggs are incubated orally. This behavior is absent in most other aquarium fish.

Meiacanthus grammistes is identified as the Blue Stripe Blenny based on taxonomic classification within the Blenniidae family. It has venomous fangs and horizontal blue stripes, which distinguish it from reef species like Firefish Goby or Royal Gramma. Scientific identification relies on fin structure, dentition, and habitat, not coloration alone.

Channel Catfish is scientifically classified as Ictalurus punctatus. The genus Ictalurus represents North American freshwater catfish with forked tails and sensory barbels. Other options represent marine or unrelated freshwater species. Scientific naming follows binomial nomenclature validated by ichthyological taxonomy.

Blue Acara is scientifically known as Andinoacara pulcher. It belongs to South American cichlids and differs from Convict or Firemouth Cichlids by coloration, aggression level, and habitat. Misidentification often occurs due to similar body shapes among cichlids.

Mikrogeophagus ramirezi is known as Ram Cichlid due to its ram-like head shape. It differs from Discus or Angelfish in size, reproductive behavior, and fin length. Classification is supported by genetic lineage and breeding behavior.

Heros severus is classified as Severum Cichlid based on body compression, banding patterns, and Amazonian habitat. Other options represent unrelated genera or African species, which differ in skull shape and breeding method.

Melanochromis johannii is identified as Electric Blue Johannii based on sexual dimorphism and electric-blue coloration. Other listed species lack the same chromatic and territorial characteristics.

Corydoras sterbai belongs to the Corydoras genus, identified by armored plating and bottom-dwelling behavior. Other options are unrelated catfish or cichlids.

Oscar fish is a South American cichlid native to the Amazon basin. African cichlids differ in breeding and habitat preferences.

Bristlenose Pleco is used for algae control due to its specialized rasping mouthparts and nocturnal grazing behavior.

Synodontis nigriventris exhibits inverted swimming behavior, which is why it is called the Upside-down Catfish. Morphologically, it differs from Corydoras or Plecos in barbels, body plating, and swimming orientation. The name is derived from observed behavioral patterns rather than habitat or feeding strategy.

Corydoras aeneus is commonly referred to as Green Cory or Bronze Cory due to its metallic coloration. It belongs to the Callichthyidae family and differs anatomically from sharks or livebearers. Identification is confirmed through body armor plates, mouth orientation, and benthic behavior.

Green Terror is often confused with Firemouth Cichlid due to overlapping size and body profile. However, differences exist in coloration patterns, aggression levels, and geographic origin. Accurate identification uses operculum coloration and fin edging analysis.

Pseudotropheus crabro is known as Bumblebee Cichlid due to its yellow and black coloration. It is a Lake Malawi species and differs genetically and behaviorally from Melanochromis or Astatotilapia species.

Melanochromis auratus is native to Lake Malawi. Geographic distribution is a key factor in species classification. Other species originate from South America or Asia.

Astronotus ocellatus is the scientific name of Oscar fish. It is identified through its ocelli markings, body mass, and South American origin. Other species listed belong to different genera and display different behavioral and morphological traits.
