Keeping Tiger Barb
The Tiger Barb grows to about 3 inches and needs a minimum of 20 gallons. Its bioload is medium, meaning it produces a moderate amount of waste for its size, a key factor the "one inch per gallon" rule ignores. It's a schooling species, so keep at least 6 together or they'll be stressed. Temperament is semi-aggressive, so avoid slow or long-finned tankmates. Use the calculator above to see how a group fits your tank's real volume before you buy.
