Platydoras armatulus
A South American catfish marked by a white stripe along each flank and rows of bony, spined plates. It creaks its pectoral spines audibly and grows large enough to need a big tank for life.
Platydoras armatulus is a doradid catfish of the Paraná River basin. A single white band runs from head to tail over a dark brown body, and rows of spined bony plates line each flank. It produces audible creaks by grinding its pectoral spines in their sockets; those spines can also pierce a hand, so move it in a container rather than a net. FishBase records a maximum of 43cm SL, while Seriously Fish gives 24cm. Seriously Fish recommends a 120 x 30cm tank (about 108 litres) at 24-30C, pH 5.8-7.5 and 2-20 dGH. Its temperament is entirely unaggressive, but it will eat fish small enough to swallow, so choose deep-bodied medium or large tank mates. It hides among driftwood by day and forages at night. There are no reports of breeding in the hobby.

120 x 30cm (about 108 litres) or larger. Provide driftwood or pipework as daytime cover over a smooth sand substrate. It grows large, so a bigger tank will be needed in the long run.
24-30C, pH 5.8-7.5, 2-20 dGH. Uneaten food collects on the bottom, so keep up regular water changes and substrate cleaning.
Not aggressive, but it eats fish small enough to fit in its mouth. It tolerates its own kind; pair it with deep-bodied medium or larger species.
Base the diet on quality sinking tablets and pellets, supplemented with frozen bloodworm and earthworms. Feeding just before lights-out works best.
There are no reports of breeding in the hobby. In nature it is said to spawn among surface vegetation.
The pectoral and dorsal spines tangle in nets and can pierce skin. Move the fish in a container of water rather than netting it.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Striped Raphael Catfish is 24〜30℃. Avoid sudden temperature changes and maintain a stable environment.
