Cascudo

Descrição

Hypostomus sp., commonly known as Cascudo, refers to a diverse genus of armored catfish belonging to the family Loricariidae. These fish are characterized by their flattened ventral surface, armored bodies covered in bony plates, and a distinctive suckermouth adapted for scraping algae and detritus from surfaces. They are primarily nocturnal and benthic, playing a crucial role in their ecosystems as detritivores and herbivores. The genus Hypostomus is one of the most speciose genera within Loricariidae, with over 150 described species, exhibiting significant morphological and ecological variation.

Informações sobre aquário

• Nível de cuidado: intermediate
• Temperamento: peaceful
• Alimentação: omnivore
• Tamanho mínimo do aquário: 150 liters (for smaller species, larger for bigger species)
• Temperatura: 22-28 °C
• Nível de pH: 6.5-7.5
• Dureza da água: 5-15 dGH
• Compatibilidade: Generally compatible with most peaceful to semi-aggressive community fish. Avoid housing with very small, slow-moving fish that could be mistaken for food, or overly aggressive species that might harass them. Provide ample hiding spots.
• Requisitos especiais: Requires well-oxygenated water with good filtration. A diet rich in vegetable matter (algae wafers, blanched vegetables) is essential, supplemented with protein sources. Provide driftwood for rasping and hiding. Substrate should be soft to prevent injury to their barbels. They are sensitive to poor water quality and require regular water changes.
