Overview
This is a large, hardy, active river schooler, so keep several together in a spacious tank; a group looks best and keeps them settled. They swim mostly in open midwater and are peaceful toward tankmates too big to be eaten, making them good company for other large, calm community fish. They are easy to feed, taking sinking pellets, flake and frozen or live foods readily. Provide at least 250 liters, and choose a long footprint with room to cruise and some current from the filter.
In the wild
The beardless barb ranges widely across Southeast Asia, from Myanmar through the Mekong to Sundaland, in streams, canals, reservoirs and other slow or still waters. Give it a roomy tank with open swimming space, a bed of sand or fine gravel and some wood or rock. It is undemanding on chemistry, doing well from 22 to 28 degrees Celsius at pH 6.0 to 7.5 in clean, well-filtered water.
Good to know
Cyclocheilichthys apogon is a silvery cyprinid that commonly reaches around 20 centimeters and can grow a little larger. As the name apogon, meaning beardless, says, it lacks the barbels that most barbs carry. It is easily recognized by neat rows of dark dots running along the scale rows and a dark blotch at the tail base. There are no aquarium spawning records for it.
Did you know
Most barbs sport at least one pair of whisker-like barbels around the mouth, but this one has none, which is exactly what its species name apogon, meaning beardless, sets out to record.
