Full Answer

The diet of specific fish within each category of herbivorous, carnivorous or omnivorous depends on what is available in their habitat. For example, herbivorous tropical reef fish will focus on eating plant matter that is available to them in a reef setting, including a variety of different kinds of algae. These fish provide an important ecological service in consuming these algae by preventing an overabundance of this microscopic plant matter, which can have a negative impact on coral growth. Similarly, predatory carnivores can have a negative ecological impact if they are introduced into non-native areas by displacing the top predator, causing a disruption in the food chain. One such example of a disruptive carnivorous fish is the snakehead fish, which has become an ecological nuisance in Maryland and Florida.

    How do you take care of a tiger barb?

    A:

    Because of their propensity to attack, three or fewer tiger barbs are best kept away from other kinds of fish; alternatively, six or more tiger barbs mostly keep to themselves in a tank with other species. With proper care, tiger barbs live three to five years. They require a moderately sized, water-filled tank and access to appropriate fish food.
