Tiger barbs are a popular freshwater fish species that is known for its vibrant coloration and active behavior. While these fish can be quite lively, they generally do not display aggressive tendencies towards other tank mates. In fact, Tiger Barbs tend to be relatively peaceful when kept with other non-aggressive fish of similar size. However, if there is not enough space in the tank or if two males feel threatened by one another, then aggression may result between them. If introducing multiple Tiger Barbs into an aquarium it is important to monitor their interactions and make sure to provide plenty of hiding places and swimming room so that none feel trapped or threatened by the others’ presence.
