The banded killifish is an incredible freshwater species found predominantly in the freshwaters of North America. It is classified as a member of the genus Fundulus and is technically known as Fundulus diaphanous. That is the controversy that has nothing to do with fishkeepers.

Banded killifish inhabit freshwater only in North America, similar to the brackish water-dwelling Mummichog.

The Banded Killifish, rare in aquariums because of its high maintenance requirements, can be a challenge to keep. 

Fundulus Diaphanous, a shoaling fish, enjoys being part of a school of three to six individuals. This species usually inhabits shallow ponds, rivers, and lakes with sandy gravel or mud bottoms. A natural habitat for these fish would also include driftwood and numerous plants.

Banded killifish are listed as threatened or endangered in certain state records in the United States. However, the population density in some areas of the U.S. makes this a regional classification only.

Banded killifish can be an eye-catching addition to a native fish tank that contains other North American specimens. Interested in keeping this problematic native fish? Below are tips to help you succeed.

What Does Banded Killifish Eat?

Generally speaking, banded killifish are carnivorous in nature. In the nature, these animals prefer to live in areas with dense vegetation, including clearings where they can collect food easily.

They eat a variety of small insects, crustaceans, mollusks, and other organisms that look like them. In terms of nutrition, the young rely primarily on copepods and larvae, mostly from the midge flies and mosquitoes.

The question now is, what makes an aquarium’s diet balanced?

It may not be as easy to answer this question as you think. The banded killifish will not accept commercially prepared food like flakes because there is a little bit of a problem.

Upon first observation, you may think this is what a newly acquired fish does. The banded and many killifish species require live foods in order to flourish, so yes, you are correct in thinking that. Unfortunately, the flakes or other commercially available foods for carnivores cannot be shifted onto them so they can become accustomed to them.

The following tips can help you ensure that their feeding is nutritious without allowing the parasites to multiply. Keeping in mind that variety always enhances nutritional benefits is also important.

Feeding Combinations

The brine shrimp provide a very good source of nutrition, especially since it contains vitamin components that are important to banded killifish food. It is also possible to use frozen brine shrimp as well as live shrimp.

Tubifex worms: They have valuable nutritional value for banded killifish, but they might be prone to parasitic infection. When you rinse them with cold tap water, you remove any parasites, so now they are ready for food.

In stores, you can find both black and white worms. Black worms have lower fat content, and they are used more frequently than white worms.

Mosquito larvae: Banded killifish feed on them for their treat. These fish tend to catch them a lot. Don’t overfeed your fish.
