Swordtail Tropical Fish
The Red Velvet Swordtail fish is an Omnivore that feeds on proteins such as worms, larvae etc. However they can eat plant and animal matter too. The react better to live food but will still eat frozen and freeze dried foods. Veggies are a bonus such as canned peas. For a steady staple food use Pellets or Fish Flakes. Feed the Livebearer species twice a day rotating between veggies and proteins. Most Omnivores need a balanced diet so if you have a few different Omnivores in your aquarium then put them on the same feeding cycle.
