Killifish in the Pet Industry

When I was young my father use to get an aquarium magazine and my sister and I use to love looking at the beautiful fish pictures. One aquarium hobbyist magazine always a section devoted to Killifish. There were colorful pictures of fish that we never saw in the aquarium stores; these fish were Killifish.

That was some 30 years ago and I have only rarely seen Killifish for sale in stores since, and even then they were not as spectacular as the ones featured on the pages of the aquarium magazines. Of course I now know that there are different levels of quality among aquarium fish, the most fancy guppies, bettas, and so forth, are never sold in stores, they are sold privately, or often in an auction, this also applies to Killifish. You can also order live Killifish from That Pet Place/That Fish Place.

Only a few varieties of Killifish are sold in stores if you can find them, with most others traded and sold privately. Killifish are sold as eggs or actual fish. They eggs can be shipped dry as certain Killifish lay their eggs before the ponds dry up so the eggs dry out under normal conditions.

Basic Information on Killifish

Killifish are fresh, and brackish, water fish, with different species found in and/or around most continents of the world excluding Australia, Antarctica, and Northern Europe. Many species are not as colorful as those featured on the pages of magazines, for example the Devil's Hole Pupfish is a Killifish.

Killifish are a type of carp and there are over 1200 different Killifish known, with more possibly yet to be discovered. 

About Keeping Killifish as Pets

As pets, or in the wild, the lifespan of a Killifish can be as short as nine months for some species, to a maximum of three years for some others. The shortest living Killifish often being referred to as “annuals”, these typically being the ones to lay their eggs in a pond that dries up seasonally, and even when kept in an aquarium that does not “dry up” they still do not live longer.

Each species will have its own dietary needs with some eating mostly algae, others eating other small fish, and many eating mosquito larvae or other insects. 

Most Killifish are under 2 inches (5cm) in length but some can get as long as 6 inches (15 cm). 

Some Killifish can live in a small school if the aquarium is large enough, while other species prefer to live in a small group with only one male.

The water conditions preferred by each Killi species will vary with some living in fresh water and others in brackish water (a mix of fresh and salt water - which can be made using aquarium salt, but not so much as to create a salt water tank). 

Of the species most commonly sold in pet stores, the Golden Wonder (from India), and Flagfish (from Florida), tend to be the best known. Note that in most places it is illegal to catch Killifish in the wild and keep them as pets without a proper permit, nor can you release unwanted pets into the wild.

Mosquitoes are Beneficial to Humanity

There seems to be a war on the mosquitoes. Some people have erroneously referred to them as the most dangerous animal in the world, the leading killer of humans. In general you will find very little love or sympathy for mosquitoes.

I want to clear up the misconception that mosquitoes are dangerous killers. Female mosquitoes bite to get blood to raise her young. Not all mosquito females do this, and not all bite humans; some prefer birds, her goal is not to kill the animals she bites, her goal is to raise her young. Humans kill pigs, cattle, chickens, and so on to feed themselves, and feed their young, with the intention of killing. If we are to think of the diseases spread by mosquitoes we must remember it is the diseases that kill, not the mosquito who happens to be the carrier, it simply picked up the organism that causes the disease from an infected source.

People need to be honest, the mosquito is not a killer, the things it carries is.

Mosquitoes are very valuable to our planet, the are a food source to many animals (and even a few plants if you think about the carnivorous plants). Frogs, birds, bats, and even other insects, eat millions of mosquitoes every day (brown bats eat hundreds every night). These species will struggle without mosquitoes and many are dying even now, the result of toxins use on mosquitoes.

One animal which we must realize depends on mosquitoes for its survival is the fish! We eat fish. Fish eat mosquitoes, particularly mosquito larvae. Young lake fish feed on mosquito larvae (so do tadpoles which fish also eat), take away mosquitoes and you take away their larvae and what do fish feed on then? 

Mosquitoes are part of our food chain, we need them, so why are we so determined to kill them?

We can protect ourselves from mosquito bites, or from diseases (in many cases there are shots we can take if going into a risky area). Some people, like myself, are lucky, we can get bit and not get a reaction, and I do have sympathy for those who do get itchy bumps, but this is no reason to hate an animal that is basically doing the same thing we do; just trying to survive and raise its young.

If we must control (not eliminate) mosquitoes, we need to do it naturally without pesticides or chemicals which could harm the animals which eat mosquitoes.
