Cuisine & Edibility

Plecostomus

Not consumed — ornamental algae-eating catfish kept as a natural tank cleaner; widely popular in freshwater aquariums for its armored body and bottom-dwelling habits.

ハナミノカサゴ

Sweet, buttery white flesh once spines are safely removed; increasingly promoted as a sustainable food source in Atlantic waters where it is an invasive species.

Species Overview

Plecostomus

The common pleco is a large armored catfish native to South America. Often purchased as an algae eater, it can outgrow most home aquariums. Its sucker-like mouth allows it to rasp algae from surfaces and anchor itself in fast-flowing currents.

ハナミノカサゴ

The red lionfish is a venomous coral reef fish native to the Indo-Pacific. Its ornate, striped body and fan-like pectoral fins make it popular in aquariums, but it has become a destructive invasive species in the western Atlantic and Caribbean.
