In aquariums Cherry Barbs can grow to be about 2" long, including their tails. Most Cherry Barbs are active swimmers and are rarely aggressive. Recommended tank mates for Cherry Barbs include, other smaller Barbs, Rainbowfish, Danios, small Gouramis, and many other small to medium size aquarium fish. Cherry Barbs are most comfortable at about 74 degrees F with a pH of about 7 with moderate hardness. It is best to house these fish in at least a 30-gallon aquarium, but bigger is better. Cherry Barbs don't need gravel, and a layer of gravel more than 1/4" thick will usually fill with bits of uneaten food that will contaminate the water.
