Relevant Information: |
H. notatus is often confused with Hypoptopomatinae sp. LG2 from Paraguay, but its body is more elongated and adult size is at least 1cm. longer. 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: The specific name notatus: Marked (L.), presumably referring to large median blackish spot on caudal fin that extends to middle caudal rays. |
