Crayfish

February 28, 2010
Louisiana Crayfish: ( Procambarus clarkii)

Size: 2-5 inches

Aquarium Size: 10-55 gallons

This article will be specifically discussing the Louisiana Crayfish, but care is essentially the same for almost any crayfish.

Crayfish are hardy animals, able to tolerate wide levels of pH and pollution. They will eat anything from fish to babies, so it’s usually a good idea to keep them alone. They will also not object to cannibalism.

Crayfish are aggressive towards other crayfish, and will seize the opportunity to gut and eat a fish that is resting. They will also uproot plants and eat them, climb cables to escape their tank, and invade foreign countries, too.

Louisiana Crayfish can be cared for in the same manner as most other crayfish can. They do well at room temperature. Don’t keep more than one together unless you have a very large tank. As mentioned earlier, they will eat anything. As a general rule, all wild caught crayfish will immediately take to bloodworms, and can subsist on this diet for a long time. You can also feed them  mussels, zucchini, lettuce, snails, and fish. It’s best to feed adult crayfish every 2 or 3 days, while younger ones can be fed every day.

Provide at least one cave or hiding spot for your crayfish, otherwise it will be stressed.

Crayfish really are easy to care for and make great pets. It’s just that they don’t get along well with others. They can live in a small tub or a 10 gallon, as long as you provide a place for them to hide. Filtration and aeration is a big plus.

To treat wild caught crayfish for random external parasites, it’s recommended to give them a 15-20 minute saltwater bath. Problem solved.

Guppy

Guppy: (Poecilotheria reticulata)                       

Size: 1.1-2.79  inches

Aquarium Size: 10-40 gallons

Guppy. Anybody who doesn’t know what this is must have a brain tumor.

It’s the guppy! These fish are great for beginners, as well as for pros looking to breed for specific traits. Being captively bred for so long, mainly in the eastern US, they can tolerate a wide range of pH. A pH of 6.7-7.3 is best. A temperature of 78-82 Fahrenheit is also best.

Breeding: Guppies breed like crazy. In fact, they produce so much offspring that can be raised so cheaply, they are used to invade and mob foreign planets, destroying, devouring, and overpowering entire civilizations with sheer mass. In this case, quantity has a quality of its own. Guppies are livebearers, and once pregnant, a female may storm sperm and produce several batches of up to 30 young through a mechanism known as super-foetation. The gestation is usually a few weeks to a month. Guppy fry are born fully formed and may be fed finely crushed flakes, newly hatched brine shrimp, or other small foods. Beware that adults usually won’t hesitate to cannibalize their own children.

You can set up a breeding tank that guppies freely breed in. For this, a 10-20+gallon is recommended, as are live plants. Some fry will be eaten, but many will survive and grow up. You may also set up a separate tank for a female to give birth in; however, this is very newfaggish and is generally frowned upon. Another option is to select a number of desirable fry and cull the rest. Do this if you are looking to breed a specific fin or color lineage; in this case, don’t buy the mutts from the local fish store. You will want to get a pure strain from a breeder.
