What does the fish 'Xiphidius' eat?

"The Xiphidius is a type of Rivulus which inhabits South American waters. Most of the fish belong to this family have dull colors, but the Xiphidius' blue and red colors catch peoples eyes"

Can anyone tell me what kind of food this fish eats?

    Rivulus xiphidius is a type of killifish. Compared to some of the other species of killies they might seem dull, but the males have a blue band (not much red to them) along the side so they aren't completely drab. You can see photos of them here:

    Like other killies, they prefer live foods - bloodworms, daphnia, mosquito larvae, fruit flies, small ants, etc. It's best to start them on live first, then you can try to add in frozen or dry foods mixed with the live to see if they'll eat these. If you can get to eat dry/frozen it's a lot more convenient for you.

    If you're planning to get these, realize they only get about 1.5 inches (4 cm) in length. A pair can be kept in as small as a 2.5 gallon tank and they don't like a lot of current, so be careful of how strong of a filter you use. They also like planted tanks with a sand bottom, and the plants will also help reduce the current. If kept in a planted tank, you might be able to get them to spawn. They prefer temperatures from 72-77oF, slightly warmer to induce spawning.

    You should also keep a cover on the tank as killies are jumpers!

    Also, this is a species which can live for more than one year - these can live for up to 3.

    In the wild they thrive off of mosquito larvae. But you can get some whiteworms, live daphnia, Drosophila larvae, but grindal worms might be your best bet.
