Gold barbs are quite hardy and undemanding of water conditions or habitat essentials. They originate in free-flowing streams and rivers, so use a powerhead to provide a decent current. Because this fish does well in colder water, it can be kept in an unheated tank.
They should be provided with a good-sized open space for swimming, along with plants, driftwood, or other decors for use as hiding spots. Use a fine-grade substrate, preferably of a darker color to showcase the colors of the fish.
Flake, pellet, freeze-dried and frozen foods will all be readily accepted. When possible, include live foods such as insects, brine shrimp, and worms of all types. Fresh vegetables are an excellent added supplement.
