Five-banded Barb Tank Setup
Give them a tank of at least 80 litres (21 US gallons). As open-water swimmers they care more about swimming length than height, so a longer tank is ideal. Keep the water at 72-81°F with a pH around 6-7.5, and avoid sudden swings. Always keep a group of at least 6 of their own kind - kept alone or in pairs they tend to turn shy, nippy, or wash out in colour.
What Do Five-banded Barbs Eat?
They're not fussy eaters - feed a varied diet, rotating good-quality dry, frozen, and gel foods rather than the same thing every day, and match the food size to their mouths.
Five-banded Barb Tank Mates
Six-banded barb; peaceful for a barb. Keep in groups of 6+. Similar to Pentazona barb. The Five-banded Barb is peaceful, which is the first thing to weigh up when you choose tank mates. It's a shoaling fish, so settle a group of 6 or more of its own kind before adding anything else - a stressed, lonely fish is far more likely to nip or hide. Before you buy, run your full stocking list through our stocking calculator. It weighs temperament, adult size, and water needs together, which a single species page can't do on its own.
Are Five-banded Barbs Good for Beginners?
Often recommended to beginners, but only after the tank is cycled and you can keep a proper school - not three fish in a new setup.
