How to hatch artemia cysts for feeding fish fry
1. Set Up:
Place hatching cone or similarly shaped vessel in well-lit area. Cone should be semi-translucent for ease of harvesting and light transmission.
2. Add Water:
Fill cone with one liter of water and add 11/2 tablespoons of salt. Optimum hatching temperature is 82°F (28°C).
3. Add Cysts:
Add cysts at the rate of 1 gram per liter.
4. Aerate:
Provide adequate aeration to keep cysts in suspension.
5. Hatch:
Depending upon water temperature, cysts should hatch in approximately 18-36 hours.
6. Harvest:
After hatching brine shrimp, turn off or remove aeration and wait several minutes for the shells and and baby brine shrimp (or nauplii) to separate. Newly hatched nauplii will settle to the bottom of the cone or move towards a light source; the shells will float to the surface. The egg shells are brown in color and the baby brine shrimp are more orange. Once separated, the nauplii can be siphoned from the bottom with a length of air tubing or gently drained through the bottom of the cone through a valve, if so equipped.
7. Rinse:
The warm incubation temperatures and metabolites from the hatching medium create ideal conditions for a bacteria bloom. Rinsing of the baby brine shrimp in a fine mesh net or sieve using clean fresh or salt water is important before feeding them to your fish.
8. Clean Equipment:
Tanks and brine shrimp hatching equipment should be cleaned and disinfected routinely.

Raising the fish fry

The fry develop in a number of minutes (livebearers) to a number of weeks. When the eggs hatch, the larvae that emerge look nothing like the parent fish. Instead, the larvae have a large, yellow yolk sac and are barely able to move, let alone swim. The larvae will feed off the egg sac until all the yolk is gone. Once the yolk sac is gone, the hungry fry will begin to look for food. The fry of small fish can be first fed infusoria, "green water," or egg yolk. Later these fry can be fed larger foods like whiteworms, Daphnia, Artemia nauplii, and ground flakes. These foods are good as a first food for slightly larger fry such as those of cichlids. Once the fish grow larger, larger foods like brine shrimp, larger Daphnia, flakes, insect larvae, and chopped Tubifex worms are accepted.

25-50% of the water in the rearing tank should be changed daily. Be sure that the "new" water added has characteristics like the water taken out, because fry are sensitive to sudden changes in the water chemistry. The fry should be fed several times a day. Many species need periodic sorting by size, so that larger fish do not cannibalize smaller fish.

With favorable water conditions, regular water changes, and generous feeding, the fry should grow quickly.

Selecting the parent fish for breeding

Once males and females have been distinguished, a suitable pair or spawning group should be chosen. There are several important traits to seek in choosing the parent fish.
1. Choose fish that display good markings and color, that should produce attractive young.
2. Only use mature, healthy fish for spawning because unhealthy fish, if they will spawn, may produce unhealthy or deformed young.
3. Be sure that the pair is compatible. Many species cannot be put together in a breeding tank and expected to get along and produce young. In fact with many cichlids, pairs form only after a group has been raised together for months if not years. In certain species, one partner will bully the other to death if there is not compatibility.
4. Avoid crossing different strains or color forms because the young are often unattractive.
5. Make sure that the pair are both of the same species because hybrids are sterile. With some cichlids and Killifish, females of different species look similar.

Sexing Fish

Determining the s*x of a fish is an important step in knowing whether one has a pair. Most fish can be classified as s*xually dimorphic or s*xually isomorphic. In s*xually dimorphic species, the s*xes can be easily distinguished by primary (shape of s*x organs) and secondary differences (size, shape, color [s*xual dichromatism], finnage). Males are frequently more colorful, larger, and have more elaborate finnage. Among the more brilliant outstanding of s*xual dimorphism can be found in Lake Malawi cichlids, Killifish, and Livebearers. In s*xually isomorphic species, there are minute, if any, apparent s*xual differences. Often, the only way to distinguish between the s*xes is the shape of the ge***al papilla, which is only visible around spawning times. In some isomorphic species, the males are slightly larger and the females are slightly rounder in the belly. Some s*xually isomorphic species have no known external s*xual differences.

History of goldfish
Goldfish are one of the first types of fish to be domesticated. There is no other way to say this, but the first fish most aquarists owned, was a goldfish. Simply because they are colorful, inexpensive, social, fun to care for and a great hobby. Now you probably want one too.
What is really going on is that these wonderful fish are descendants of the Prussian carp, which is a native to the eastern and southeastern part of Asia and part of the Cyprinidae family. You know, everything about goldfish began about one thousand years ago in the Song Era when the ancient Chinese started to breed carp. Originally, the carp had scales that were silver in color before the breeding. After that, the there was a color mutation to yellow-orange scales. Yellow was the imperial color.
Did you know that this new colored version of the Carp, known as goldfish today was forbidden and could only be kept by royal families? Yes, this is probably the reason why there are more orange goldfish than yellow ones these days. Or maybe not.
Goldfish only became popular outside China, in the early 16th century, in Japan. Here, two beautiful varieties were developed: Tosakin and Ryukin. Later, in the 17th century, the goldfish was introduced to the southern countries of Europe. Finally, in the 1850's it became popular un the United States. Home of the well-known Comet goldfish.
Goldfish species are the only species in the animal kingdom that were manipulated to give such grotesque and funny appearances. Presently, there are 18 varieties of goldfish, all beautiful and cute. They can be found in colors like orange, yellow, blue, red, white, black, chocolate, calico or a beautiful mixture of these.

"Preparation to breed discus fish"
Discus will readily reproduce in the aquarium but you may need to dedicate months, even a year (if you start out with juveniles) to the prospect. Until recently they had only successfully been bred in captivity a few times and only then by dedicated individuals. However very recently hobbyists have had widespread success breeding discuss by following a few key steps.
A Discus couple will not spawn in an aquarium that is too shallow. You will need a depth of at least 15 inches due to their tall shape. Smaller 15" cube aquariums can be used for breeding especially because they allow close contact of the breeding partners. However a deeper 36 inches x 18 inches x 18 inches aquarium would be spacious and humane for a suitable breeding pair.
Make sure the temperature is above 82 F, it needs to be a warmer climate to try and coax them into mating behavior. Replicating the summer and therefore 'rainy' climate of the amazon is a common tool in breeding aquarium fish.
The pH will need to be kept as close to 6.5 as possible and as stable as possible. The summer amazon rainstorms collect substrate and mud in the wild softening the water. The aquarium water will need to be as soft as possible from 1-4dH. Soft water has poor buffering ability hence it is important to check the water each day to ensure the parameters remain stable (especially pH). You will need to keep nitrates at a minimum by performing water changes every week and siphoning out the waste. About 30-50% will be perfect. These water changes are important and also signify breeding conditions to the breeding Discus.
When feeding breeding Discus, protein rich foods are the best choice. Diversifying food sources will help to balance the Discus diet. Professional breeders use beef heart but this should also be combined with bloodworms and vegetable matter such as spinach to aid in vitamin uptake. To keep them in good health use some high grade tropical granules twice a week to supply them with the required nutrients and vitamins they may be lacking.
Placing an upturned clay pot or cone in the discus tank will give a hard surface for the discus to lay eggs on. Be sure the surface is clean and will not pollute the aquarium. Professional plastic cones are sold on line that have been used with proven results. These may be a good consideration to increase laying chances.

History of Discus Fish
It was the first quarter of 19th century when Discus fish were first discover in the waters of Brazilian Amazon River as well as surrounding flooded lakes and rivers. Shortly, Discus fish were introduced to the aquarium hobby and imported in Europe and the Unites States in the mid 1930’s. The early efforts to import and keep Discus fish were extremely challenging. Before the 70’s we were limited to Wild Blue, Green, Heckle, and Brown Discus. It was until the late 80’s and early 90’s when we saw new Discus breeds and color varieties such as Blue Diamond and Snake Skin. Today, many types of Discus fish are popular as aquarium fish in many countries and particularly in Asia. Additionally, we know exactly the secrets of breeding and keeping Discus fish in home fish tank that considered impossible in the past.
Today, the latest aquarium equipment made Discus fish keeping simple if you know the correct treatment and attention in particular areas.
