How hard are they to keep?
We would class Stiphodon atropurpureus as a moderate care level fish. They are best suited to aquarists who can provide clean, well-oxygenated water, a mature aquarium and plenty of natural grazing surfaces.
What is its maximum size?
Stiphodon atropurpureus typically grows to around 5–6cm in length.
Where are they from?
They are native to freshwater streams and rivers across parts of Southeast Asia and nearby western Pacific islands, where they inhabit clear, fast-flowing waters with rocky substrates.
What are the ideal water conditions?
Ideal water conditions are a temperature of 22–28°C, with a pH of around 6.5–7.5. They require excellent water quality, strong oxygenation and a good flow of water. A mature aquarium with smooth rocks and plenty of surfaces for algae and biofilm to grow is highly recommended.
What do you feed them?
Stiphodon atropurpureus naturally grazes on algae and the microorganisms living within it. Offer a varied diet that includes algae-based foods, spirulina, suitable sinking herbivore foods and specialised grazing wafers. A mature tank with natural algae and biofilm is particularly important, as some individuals can be reluctant to accept prepared foods.
How compatible are they with other fish?
They are generally peaceful and can be kept with other small, peaceful fish that enjoy similar water conditions. Avoid aggressive or much larger tank mates. Males may display territorial behaviour towards one another, so provide plenty of rocks, grazing areas and hiding places. They are best kept in a suitably sized aquarium with ample grazing space and good water movement.
