Keeping Gars A short review

By William Berg of Sweden, for

If you take a quick look at this species they don't seem like aquarium fishes. They are large and highly predatory. But then again, these are qualities that attract some, like me! If you've been keeping aquariums for a while and haverepparttar room to keep large predatory fishes I recommend you try these fish, but not until you've done your homework and knowrepparttar 125838 gars' requirements and what you are getting yourself into.

Species of gar:

Florida spotted gar, Lepisosteus platyrhinchus A highly varied species of gar. Has more spots on its body and a shorter snout than many other gars. Easily mistaken for spotted gar.

Spotted gar, Lepisosteus oculatus Long snout and spots. Spots to a higher degree towardsrepparttar 125839 posterior of its body. Easily mistaken for Florida spotted gar.

Shortnosed gar, Lepisosteus platostomus The shortnosed gar can be identified by its short snout, and byrepparttar 125840 lack of teeth rows inrepparttar 125841 upper jaw likerepparttar 125842 alligator gar, andrepparttar 125843 lack of spots on its body.

Long-nosed gar, Lepisosteus osseus The long-nosed gar is, asrepparttar 125844 name suggests, identified by its long slender snout, and also by its slender body.

Alligator gar, Atractosteus spatula The alligator gar has a short broad snout and two big rows of teeth inrepparttar 125845 upper jaw. This species is spotted onrepparttar 125846 posterior part ofrepparttar 125847 body and to a lesser extent on other parts ofrepparttar 125848 body.

Tropical gar, Atractosteus tropicus A very rare species.

Manfari or Cuban gar, Atractosteus tristoechus Looks very similar torepparttar 125849 alligator gar and since it is very rare inrepparttar 125850 trade you can usually assume that your gar is an alligator gar and not a Cuban gar unless otherwise stated. The Cuban gar has a broader snout and lacks pattern on its body.

Beside these species there are a number of hybrids such asrepparttar 125851 crocodile gar.

Spotted, Florida and short-nosed gars are smaller thanrepparttar 125852 other species and may be more suitable for aquariums. They usually don't grow larger than 2 feet in aquariums. Long-nosed and alligator gars grow to a very large size and larger ponds are recommended if you'd like to keep fully grown specimens. So if you don't have (or plan on getting) a large pond, stay withrepparttar 125853 smaller species. Even withrepparttar 125854 smaller species you are still going to need a rather large aquarium. The tropical gar also is possible to keep in aquariums as it doesn't grow as large; however this species is very hard to find. The Cuban gar is a red-list endangered species and shouldn't be kept even if you somehow find one.

Breeding Crayfish

By William Berg of Sweden, for

Inrepparttar text below I shall try to give a short overview of some ofrepparttar 125837 basics when breeding crayfish. Particular species may have other behaviours and demands. It should be said that my main experience as an aquarist is with relation to fish, but I shall try to convey what little knowledge I have.

Sexing Crayfish Sexing crayfish isn't always easy. The genital openings are located in different places onrepparttar 125838 body depending on whether it's a male or a female. Males have their genital openings behind/under their posterior pair of legs. Females have their genital openings underrepparttar 125839 third pair of legs counted fromrepparttar 125840 posterior. However, many individuals have a male as well as a female genital opening, makingrepparttar 125841 sexing much more complicated. But these are always either male or female; usually male but you can't be sure.

Mating and egg carrying In aquariums, spawning is possible any time of year. The male makes a little sperm packet and places it onrepparttar 125842 female's stomach. The female then spawns her eggs, passing them throughrepparttar 125843 sperm packet so thatrepparttar 125844 eggs get fertilized. It is not uncommon forrepparttar 125845 female to lose a claw during this process. She then placesrepparttar 125846 eggs under her tail where they will be kept until they are ready to be released. How long this will be depends onrepparttar 125847 water temperature andrepparttar 125848 species, but it will be at least 4 weeks. A lot of other factors can also affectrepparttar 125849 length ofrepparttar 125850 egg carrying period, such as water quality, and food supply and quality. The mother will watch overrepparttar 125851 young for a short time after birth.

Fry The fry are very small when they are born but are fully developed miniature crayfish. Fry are usually detritus feeders, which means that they will feed on any decomposing plant parts and food leftovers they can find while scouringrepparttar 125852 bottom. Vegetable food is preferred and they can be fed boiled lettuce leaves that are left to decay inrepparttar 125853 aquarium. Be aware ofrepparttar 125854 water quality. Fry are often very cannibalistic and a large aquarium is required if you want a higher number of fry to survive. Sorting fry for size may helprepparttar 125855 survival rate.
