Relevant Information:

Description: Hisonotus iota differs from its congeners, except from Hisonotus hungy, by the lower lateral plate count 20–22 (mode 21) vs. 22–29 lateral plates, and by the lower vertebral count 25–26 vs. 27–32 vertebrae. It differs from Hisonotus hungy by having an infraorbital canal entering the infraorbital series via the compound pterotic vs. infraorbital canal entering the infraorbital series via the sphenotic. Reproduction: Scatters eggs throughout the aquarium and are not cared for by the parents. Aquarium Care: Said to be a bit more problematic in the aquarium if good water quality is not adhered to. They rest on aquatic vegetation in the aquarium so long leaved plants are recommended. Cooler temperatures and a strong filtration with adequate current will fare better for this species and for this genera overall. Diet: Will feed on flake, algae, tablet foods and algae wafers. Etymology: iota (?), smallest letter of Greek alphabet, i.e., anything very small, referring to its small size compared to congeners.
