What is killifish by Tyrone Genade

The word killifish is a modification of the Dutch term “kil vissen” that literally means “stream fish”. The first killifish was the mumichog Fundulus heteroclitus, which was discovered in a stream near New Amsterdam (modern day New York). This word, killifish, is now widely applied to all egg-laying  members of the order Cyprinodontiformes. Also belonging to the order Cyprinodontiformes are the American live bears such as guppies, mollies, platies and swords—and the least killifish Heterandria formosa. The ricefish (Oryzias species) are today placed in the order Beloniformes but is afforded honorary killifish status for old times sake. Both orders are regarded to be closely related to the Atheriniformes (rainbow fish and blue-eyes). As evidence of this, is the potential for eggs of the blue-eyes Pseudomugil species (of the order Atheriniformes) to enter a delayed state of development akin to diapause. Eggs of Pseudomugil gertrudae and mellis are able to extend their incubation 100% (from two to four weeks) when incubated in damp peat instead of water. The eggs of Pseudo

mugil cyanodorsalis can remain undeveloped for extended periods of time in full strength sea water, only beginning to develop in the presence of fresh or brackish water. The eggs of killifish, while not normally tolerating sea water, react similarly to an increase in salinity. Previously all the killifish fell under the family Cyprinodontidae but have since been split up into several diverse families. The lamp-eyes now fall under the family Poeciliidae along with the guppies and mollies. The Aphyosemion, Epiplatys, Aplocheilus and Nothobranchius are now of the family Aplocheilinae and the Rivulus and the former “Cynolebias” species

now under Rivulinae. The various Fundulus types of North America fall into their own family Fundulinae. Then there are the families that include the pupfish and Aphanius etc. . . There are approximately 700 species of Cyprinodont. Where in the past the taxonomy represented the morphological and meristic similarities, today

it represents the hypothesized evolutionary lineages. This implies that all fish belonging to the same genus share a common biology that is more closely like each other than any other species group. While not to claim that the

science is unimportant, the real issue for us as fishkeepers is that if we know something about the care of one member of the genus we can reasonably assume the same characters are possessed by a species you know nothing about within that genus. When beginning to experiment with a new species these assumptions are invaluable in approaching the question of how to care for your new charge. Another conformation adopted by the author, is to where ever possible, use the currently accepted sub-generic name for a group of fish. While some ichthyologists reject the genus name Chromaphyosemion1 as a valid genus name for the fish that were the bivittatum-group of the genus Aphyosemion, this author does recognize the validity of this name. The reasoning is simple: the fish of the genus Chromaphyosemion resemble each other more closely in form and physiology, than they do other members of the super genus Aphyosemion. Likewise, the names Diapteron, Kathyetys and Mesoaphyosemion will be used to descriptively group those particular members of Aphyosemion.

In summation, to the hobbyist’s mind a killifish is a Cyprinodont that lays eggs. That lamp-eyes are more closely related to livebearers than Aphyosemion doesn’t make them any less a killifish.

Medaka skills, Loach fish – to prolong life in the longevity of your aquarium fish

The fish can be said to be similar for all groups need food, water, cleaning, oxygen, and need care and love of other prosper. Since the main source of water to ensure its survival.

It is a peaceful nature, and thus a very good life in a community tank.

fish species of Botia Loach Acnthophthalmus Semicinctus Macracantha and Cobitidae group, those who are most easily found in pet shops families. The species Botias is usually the easiest way to take care of fish Loach. Live in moderate hard water or alkaline water, so avoid acid water. Water temperature 70 degrees Fahrenheit must be flat, and 75 degrees Fahrenheit, the highest maintenance. The Tiger Botia including clown fish tank in the community welcome. You can learn about online research or ask your local supplier of fish and more.

Loach as coolies

water condition of choice is a bit ‘cool Loach or neutral water, no special requirements and the pH of acidic waters. This was a very shy fish, not for your aquarium lights should make these fish have plenty of room to hide dense many plants.

From the family Cyprinodontidae Medaka fish. These fish because they have all the characteristics of available freshwater and marine fish with bright colors more widely distributed. This is a good starter fish, as the fees and the public tank. They are usually sub-Saharan habitat in Africa, although these flows to dry in a particular season, but eventually the fish died. However, it is spawning children grow up well, dry climate, restoration of Medaka. These fish live in small tanks and water conditions are good to 70 degrees (favorable, will live longer at this temperature) to 85 degrees Fahrenheit. Medaka can grow to 2-4 inches in size.

Cooley loach water conditions preferred

Cooley has a slight acid water or water of neutral pH, there is no preference. Tank conditions: Shy fish do not like lights, so you should give him a home aquarium plant dense with plenty of areas to hide.


Cooley party away the joy of the worm, but he will eat, frozen foods, as well as a selection of dried foods.

Killifish from the Cyprinodontidae family. The fish is widely distributed, with the bright colors of all freshwater and saltwater fish. This fish is ideal for beginners, because they want to live in community tanks without problems. The habitat of fish in the waters of sub-Saharan Africa.Streams dry in certain seasons, the fish died. However, future generations a better life or to lay their eggs in dry weather, we relive the Medaka.

The fish live in a small tank, and willing to water conditions, 70 degrees or 85 degrees Fahrenheit. The longevity of fish in the temperature of 70 degrees. Latipes grow to 2 or 4 inches in size.

Water Conditions

Peat filtered water is ideal, but the fish would tolerate soft, hard, or slightly acidic water.


The fish you eat a variety of freeze-dried foods. Disadvantage is that killifish rarely found in breeding pet store. The well-known (U.S. latipes Association) group can help find places to sell fish.
