African Cichlids Fish





First off, cichlids is pronounced “Sick-Lids”. African Cichlids are fish found in Three lakes in Africa; Malawi, Tanganyika and Victoria. The Victorian Species are less numerous and usually less colorful than the others. These fish usually grow to about six or seven inches long, with the exception of the Frontosoa Species, which grow to about twelve to fourteen inches in length. Fortunately, these fish are freshwater, and easy to raise in a home aquarium, the only requirement being that they have water with a higher pH level and plenty of hiding spots (they can be quite aggressive!). There are also species of Cichlids that live in the Amazon Basin, but these get much larger and are much more aggressive than their African relatives.

Coral Beauty Fish





A small angelfish, usually available at your local pet store, they really are a fish one needs to see in person to have a full appreciation of their color. These fish are usually keepable in any marine aquarium and are very hardy.

The Siamese Fighting-Betta splendens

For hundred of years, the Siamese Fighting Fish or Betta splendens, has been kept and cultivated by people in Thailand (Siam). Today, the Betta is popular throughout the world – though not for the purpose of fish fighting but as a peaceful aquarium resident. Through years of selective breeding, pet store Bettas look vastly different from their original, wild-caught ancestors. Instead of just a few colors, they can now be purchased in an array of hues including red, blue, turquoise, black, white, yellow, and brown.

In addition, their fins have greatly increased in size and are much more elaborate; among the different types of hybrids available are the Veil Tail, Delta Tail, Half Moon, Double Tail, and Crown Tail. Of course, it is only the males that have the long, elegant fins and do all the fighting. Females have much shorter fins and are not as vividly colored as the males. Interestingly, Bettas are air breathers; they use a unique organ called the labyrinth to process the oxygen in the air and they will die if they are unable to reach the waters surface.

The Betta’s native habitat is the warm, still ponds, swamps and rice paddies of Southeast Asia. There, among the leaves and branches of the dense undergrowth, these carnivorous fish hunt for small insects and larvae.

Although the Bettas found in pet stores today have been captive bred, they should be kept in conditions that mimic their ancestor’s natural environment. Therefore, an aquarium (minimum size of 10 gallons) that is decorated with several plants and that has gentle water movement will suit them best. A cover, with a few small openings to allow air circulation, should also be provided to prevent them from jumping out.

Bettas like warmer temperatures so the water in the aquarium should be kept between 76-85 F with a slightly acidic pH of 6.5-7.0. Their diet should consist primarily of meaty foods such as brine shrimp, bloodworms, freeze-dried tubifex worms, etc. Bettas can grow to 3 inches long and live for up to 3 years if cared for properly. As far as tank mates are concerned, Bettas get along fine with most fishes; but do not keep them with aggressive species or any that are prone to pick at their beautiful fins. Male Bettas can be kept together in the same tank only if they are partitioned off from each other – otherwise you can expect some shredded fins, missing scales and not-so-nice looking fish

Twin Spot Wrasse (Coris aygula)

The Twin Spot Wrasse or Coris aygula is just one of the over 500 different species of Wrasse fish on the planet! This saltwater fish can be differentiated from other species by the two dark spots that adorn its dorsal fin when it is young. It will also have a silver coloration with dark spots on its head. As it grows older, it will turn a dark bluish green and develop a white or green band around its body. They will look like a totally different species to tell you the truth.

Cave Transparent Goby (Coryphopterus glaucofrenum)

The Cave Transparent Goby or Coryphopterus glaucofrenum is a saltwater fish that makes a great addition to most aquariums. This fish is considered to be very easy to take care of, and is certainly interesting to watch. As you can imagine with a name like the Cave Transparent Goby, this fish has a body that is partially transparent along with a series of orange spots that cover its entire body, including its head, fins and tail.

This species of Goby is native to Maldives where it is found around reefs. In an aquarium setting this fish only requires about a 10 gallon tank with the following water conditions, 72-78° F, dKH 8-12, pH 8.1-8.4, sg 1.020-1.025. Like most other Gobies, this fish is quite small, only growing to about 3" in maximum length. Make sure you don't keep similar Gobies in the same tank unless they have plenty of room. They will attack each other if not given enough space. These fish should be fed brine shrimp, table shrimp, mysis shrimp and other frozen meaty foods. If you provide them with branching coral you don't need to feed them quite as much.
Cave Transparent Goby fish are known to spawn in an aquarium setting. Giving them a cave will increase your chances of success. This saltwater fish will lay its eggs on the ceiling of the cave and before you know it, you will have little Cave Transparent Gobies swimming around.

Emperor Red Snapper (Lutjanus sebae)

The Emperor Red Snapper or Lutjanus sebae is yet another saltwater fish that changes its colors over its lifetime. When this species of Snapper is young it has a series of red and black stripes set against its white body. As it grows larger, these stripes tend to fade, and eventually disappear. By the time it is all over, the fish is a reddish pink and looks completely different then it did when it was younger.Also known as the Sebae Snapper, this fish grows quickly, reaching about 2-1/2' in maximum length over its lifetime. Even though they get this large, people still try to house them in an aquarium. One of 200 gallons or more is highly recommended with the following water conditions, 72-78° F, dKH 8-12, pH 8.1-8.4 and sg 1.020-1.025. They are not considered to be very easy to care for and should be kept alone with plenty of room to swim. This fish should be fed a meal of meaty food chopped up like shrimp, fish and scallops daily to keep it healthy and happy.

They require at least a 80 gallon tank with the following water conditions, 72-78° F, dKH 8-12, pH 8.1-8.4 and sg 1.020-1.025.

The Dalmatian Molly or Poecilia latipinna is also known as the Marbled Molly and has the ability to survive in freshwater or saltwater.
