Recognizing the Striking Patterns of American Flagfish
Identifying American Flagfish, which is a type of killifish from the family Cyprinodontidae, in a sea of fish is easy because of its vivid red, white, and blue-green coloration despite being only ~2 inch (5 – 6 cm) long.
But that’s not its most interesting physical feature.
This species has a unique dimorphism that makes color intensity in males and females different!
Color Pattern
Yes, all Jordanella floridae appearance resemble each other being American flag, but the patterns aren’t uniform between sexes, as mentioned, or from fish based on heredity and health factors.
| Females | Males |
| Dull shades of green and brown with less red marks | Bright greenish-blue scales with red stripes and iridescent glow |
Unique Traits
Besides their obvious colorful aquarium fish traits, American Flagfish are natural algae-eaters. Meaning they can control algae growth without you resorting to chemicals. These fish chomp away at the most annoying hair algae outbreak I had some time ago.
Crafting the Perfect Aquarium for American Flagfish
An ideal habitat for Jordanella floridae should mimic the slow-moving waters of Florida. Florida Flagfish (As American Flagfish are also called) can be naturally found in a pond, ditch, marsh, or stream with dense vegetation. In your home tank you’ll need clean water and natural lighting to complete the Floridian look alongside a well aquascaped layout.
So, here’s how to build the perfect American Flagfish tank setup.
Tank Size and Layout
Get a minimum of 20 gallons for a pair of adults and set the water flow to a slow, moderate current. Add plants to give the tank a dense look.
Keep reading for more info.
Water Parameters
Here are specific temperature, pH, and water hardness ranges in an ideal American Flagfish tank.
| Temperature | 64 – 86℉ |
| pH level | 6.5 – 8.5 |
| Hardness | 6 – 20 dGH |
Without maintaining proper water parameters, the tank’s water quality can degrade, which can cause a wide range of issues from cloudy aquarium water to illness and mass die off.
Aquarium Decor
Your planted freshwater aquarium design is the icing on the cake when building an ideal Floridian tank.
- Plants: Use floating aquatic plants like Water Lettuce to create shade, stem plants like Hornwort for hiding, leaf litter for density, rooted plants like Vallisneria for structure, and algae for natural grazing.
- Rocks: Only smooth and round stones that look like riverbeds or soft stones like marsh suit this pet. You can also use natural decor like coconut shells to create resting spots for breeding.
- Driftwood: Use this to encourage natural algae growth grazing and create hiding spots for your American Flagfish.

Feeding American Flagfish: A Balanced Diet or Vibrant Colors
Although American Flagfish have an algae-focused preference, that’s not the only food they need as omnivores. To get the best nutrition for vibrant aquarium fish, you must combine algae, plant matter, and protein-based foods in measured quantities.
Use this Jordanella floridae diet guide for the best outcome.
Diet Suggestions
Serve your American Flagfish plant matter and algae as a staple food and supplement their diet with high-quality pellets, frozen and live foods like small invertebrates (brine shrimp), and blanched vegetables like sliced cucumber, spinach or zucchini.

Feeding Tips
Use a strict regimen when feeding American Flagfish. Give them enough portions to finish within a few minutes to prevent waste and overfeeding.
Tank Mates for American Flagfish: Peaceful Coexistence
You must consider the semi-aggressive trait and other unique features when choosing tank mates for American Flagfish. Feeding, environmental needs, size, and social habits all factor into the Jordanella floridae compatibility with other tank mates.
I recommend some peaceful and resilient species for community aquarium setups.
Compatible Species
- Corydoras
- Mollies
- Danios
Avoided Species
Keep your American Flagfish away from long-finned fish like guppies, bettas, and species that hate slow-moving waters.
Arthur’s Note: Be forewarned American Flagfish can be very aggressive. Remember those American Flagfish I mentioned that I had and that would happily chomp away at resilient hair algae, well once they sexually matured, they picked up a habit of chomping away at their tankmates! If you keep American Flagfish in a community tank be on the lookout for early signs of aggression and address them early.

Using this long-term fishkeeping guide means you’ll enjoy your American Flagfish’s company for 3-5 years at most.
Breeding American Flagfish: From Eggs to Fry
You can use the same parameters as a regular tank for breeding American Flagfish but focus on dense plantations and caves for spawning.
This is where your identification knowledge becomes useful because you must choose at least one male and female adult American Flagfish to reproduce more of these patriotic species.
Their breeding habits become relevant, and so do these tips for successful reproduction.
Breeding Setup
Useful Jordanella floridae spawning tips I recommend include using fine-leaved plants in the breeding tank. Also, a spawning mop should be added to the cave to give the eggs surfaces to adhere, and a sponge filter should be used to prevent them from going with the strong current during filtration.
Fry Care Tips
The fry will first eat their yolk sac once the eggs hatch in 5 to 10 days. Then, you must feed them powdered dry food, vinegar eels, baby brine shrimp, or infusoria until they grow strong enough to eat adult foods.
Improper fry care for freshwater fish leads to health issues and malformations. So take this seriously and keep the tank maintenance optimal to accommodate their sensitive nature.
Preventing Health Issues in American Flagfish
American Flagfish face common health issues such as fin rot and stress caused by poor water conditions and low-quality maintenance. Aquarists need to do their best with American Flagfish health care.

Preventative Measures
Preventing fish diseases is simple when you focus on the factors that can lead to common health issues. Keep the water clean, provide a balanced diet, reduce stress-inducing factors, and stabilize the water conditions.
Signs of Illness
Three common signs that your American Flagfish is sick are:
- Physical Changes: Discoloration, Damaged fins, Spotted scales, and Cloudy Eyes
- Behavioral Changes: Appetite Loss, Lethargy, Erratic Swimming, and Scratching
