Bluefin Killifish California: Overview
The bluefin killifish is an ancient species that resembles Fundulus but with more of a spindle-shaped body. In aquariums, they rarely grow bigger than 5 centimeters, but they do reach a maximum of 6 centimeters in some cases. Their bodies are oval in shape. The fish has an elongated, streamlined body. It is about a quarter of its length from the nose to the caudal peduncle.
Their dorsal fin begins halfway down their body. A small anal fin extends to the rear of the animal. The nose is rounded; the mouth terminal has an upwards-pointing mouth opening. A critical difference between the Lucania and other Fundulus-type species is its two rows of teeth. The lifespan of these creatures seems to be around two years.
The bluefin killifish is found in North America, mainly in Florida (except west of the Choctawhatchee River delta) and, on a rare occasion, down the Atlantic coast to central South Carolina and in southeastern Alabama in the Chipola River delta. It was also reintroduced into the wild in California, Texas, and North Carolina.
The pH value of subtropical freshwater is between 6.5 and 6.8 due to humic acids, and the temperature is between 12 °C and 22 °C.
Typically, they live in lakes, swamps, ponds, pools, and streams that tend to have dense vegetation. These environments are frequently near-natural wells.
Schoolchildren usually swim pretty deep below the surface of the water. This is not a seasonal fish, despite being in the killi family. Aquarians can keep it fairly comfortably.
Bluefin Killifish Care Guideline
The bluefin killifish is a popular choice among fish keepers because of its ease of care and relatively low price. However, proper care is essential to keeping this fish healthy and happy. This guideline provides tips on how to care for a bluefin killifish tank, including feeding and water changes.
Typically, this species lives in the still marshy waters of Florida. Lucania goodei doesn’t live in the same swampy, more brackish coastal areas.
This area has almost tropical temperatures during the summer but is often very cold during the winter. Because of this, they can withstand temperatures as low as 5 ° Celsius and as high as 25 ° Celsius.
Suppose you’re going to maintain this tooth carp. In that case, it’s best to do so in an unheated aquarium at room temperature, together with other species that live in the same environment, such as Elassoma everglades and Jordanella floridae, according to some accounts. Keeping fish in a tropical community tank worked great for me, but I can’t rule out the possibility of lower lifespans if the temperature is kept too high all the time.
A substantial layer of humus should cover the bottom of the aquarium (peat, for example), and the aquarium should be heavily planted with plants such as Myriophyllum, Najas, Bacopa, and Heteranthera. Their favorite food is insects and insect larvae, but they will eat small invertebrates (daphnia and cyclops) and dry food.
It is advised not to transfer them directly from one aquarium to another because they are susceptible to changes in water composition. Tap water is less tolerable for them than supplements with rainwater.
Breeding temperatures above 23-24 °C fail to successfully fertilize most eggs, whereas 18 to 19 °C is the optimal temperature for successfully fertilizing sperm.
Mating can be quite intense, as it usually is in closely related species. A variety of fine-leaved leaves, both above and below the surface of the water, are deposited with eggs. They spawn daily for several consecutive weeks, but they lay two to five eggs per spawn. The eggs can measure 200 in number.
They hang from plants with short slime threads and are yellowish-brown in color. Hatching can take one week to ten days, depending on the temperature. The fry grows reasonably quickly, and we see the red tail develop in the males after about five to six weeks.
The diet of bluefin killifish is one of the most critical aspects of their ecology. Bluefin killifish are known to feed predominantly on plankton, but they also eat small fish and invertebrates. Knowing which types of prey these fish consume can help you better understand their ecology and behavior.

How big do bluefin killifish get?
In normal conditions, bluefin killifish grow to a length of 2.9 cm (1.1 in), but the largest one measured was 6 cm (2.4 in).
Are killifish top swimmers?
Killifish are often slender and have a pike-like shape, which is a benefit to swimmers. Others have long and broad fins, while some have a cylindrical shape with short, rounded fins.
Where can I buy bluefin killifish?
There’s no doubt that bluefin killifish is one of the most sought-after fish around. Unfortunately, they’re not always easy to find. If you’re looking to buy some in person, your best bet is probably a local fish market. Alternatively, online retailers such as Amazon often have them available.
In conclusion, knowing the bluefin killifish California is a great way to increase your chances of success while fishing. Knowing the different habitats they inhabit and when they are most active can make all the difference when targeting this fish. So, ensure to keep up to date on information by checking out resources like this one. Finally, if you want to catch these fish, practice patience and preparation – these little guys are some of the hardest to land.

Annette grew up caring for and breeding African Cichlids, which led to a hobby in high school that doubled as a profitable means. Attending Reed College gave her time to solidify herself as an accomplished aquarium caretaker with an eye for sales. After that, from 2009 – 2013, she studied at Roger Williams University – one of the most prestigious universities for Aquaculture and Aquarium in USA. She is the founder of AquariumCircle since 2010
