How Many Tiger Barbs in a Planted 10 Gallon Aquarium?

Honestly I wouldnt recommend putting tiger barbs in anything less then 20 gallons.Tiger barbs are feisty fish, and grow larger than you probably realize. A 10 gallon tank is really not appropriate. Because they are aggressive, they are also best in larger schools although 5 is the minimum for a school, and a 10 gallon isn't enough space. A 10 gallon would be sutiable for 6 cherry barbs though.
