American flagfish belongs to omnivore that eats algae, crustaceans, and insects for diet. Therefore you should provide the same food as what it consumes.

In the wild, this species likes feeding on plant matter, so don’t forget to supply fresh vegetables in the home tank.

Algae is the based food for flagfish that should be provided in several weeks. Instead of that, it is necessary to feed it on fresh vegetables such as zucchini, cucumber, and shelled peas.

This species becomes sought-after fish since it feeds on hair algae. Thus, the flagfish might control the aquarium from this plant matter.

However, they can damage any aquatic elements in the aquascape tank.

Additionally, flake food is high-quality nourishment for this small kill fish. Also, live or frozen supplies become the other alternative diet that includes blackworms, Daphnia, and brine shrimps.

Brood of Juvenile Fish

To achieve a successful propagation, prepare a separate breeding tank. It provides a proper condition to breed and protects the juveniles well.

Set up a small breeding tank with a size of 61 centimeters. Control the temperature higher than common condition, for about 22 degrees Celcius. Utilize sponge filters to provide soft filtration. They are to ensure that the fry can hatch safely.

Don’t forget to apply for a small and thin substrate in the foreground. It serves a comfortable area for the juveniles to avoid getting stuck in the gravels.

Furthermore, decorate some floating plants for hiding areas. The females need those sites to stay when they are not ready to propagate with over-enthusiastic males.

During the breeding process, the females need a short time to rest. Thus, the floating plants serve the best hiding place for them.

The breeding of flagfish occurs during the fall and spring seasons. To avoid having many aggressive males during the propagation, identify the genders are necessary. Both males and females have their specific characteristics.

The females feature a large and fleshy yellow body with a black marking on the dorsal fin. Meanwhile, the males have a more colorful appearance without any dark spots. The big flat thin part on the back is as big as the anal ones.

The process starts with setting up the males’ territories to tempt the females into the denning site. Then, both fish will copulate in the territorial area.

After doing a successful display, they find an aquatic plant or hardscape. The male will start bouncing motions over the female to release the eggs. Both genders try to keep jerking several times.

American flagfish has two types of spawning. They are depositing the eggs in the substrate and the roots of the floating plants.

This fish usually scatters the eggs widely instead of digging out holes for parental care. Then, after breeding, remove the parents to maximize the number of juveniles.

The eggs will hatch after ten days. Then, the young fishes will stay at the bottom of the aquarium since they cannot swim due to the early brood of the fry.

You can feed them with baby brine shrimps and micro worms. However, it takes many efforts to give them foods properly.

Guppy is a rainbow fish that can be paired with American flagfish. This slow-swimming species will balance the energetic speed of Cyprindon floridae.

However, to prevent the kill fish bite Poecilia reticulata, establish an aquascape with some driftwoods and rocks to break the flagfish’s line-of-sight. It is better to add a school of five male guppies as the tank mates.
