Great swimmers in my aquarium

 Maylandia lombardoi - Origin Africa

Kingdom   : Animalia
Class         : Actinopterygii
Order        : Perciformes
Family       : Cichlidae
Sub-family : Pseudocrenilabrinae
Genus        : Maylandia (disputed)
Species      : lombardoi

Common name :

 lombardoi, kenyi or kennyi
Description : 

Maylandia lombardoi, is a 13 cm (5 in) freshwater fish from the family Cichlidae. This mbuna species is popular in the aquarium hobby where it is sold under a variety of common names including: lombardoi, kenyi or kennyi. The correct name of its genus is not clear; some authors prefer Maylandia, others Metriaclima.

It is endemic to the rocky shores of Mbenji Island, Lake Malawi in east Africa. The species is highly sexually dimorphic, females and juvenile males are pale white-blue with several blue-black vertical bands extending into the dorsal fin. Adult males turn bright yellow with faint brown bars crossing the body; fins are plain yellow with egg spots on the anal fin. Like most mbuna cichlids, this species is a maternal mouthbrooder. When mouth brooding, females may defend a small territory and assume the colouration of males. Like other mbuna, these fish can be very aggressive and males may end up killing other tankmates. To prevent casualties, the aquarium should be spacious and rocky with several hiding places. A single male should be kept with several females. When breeding, females hold the eggs and fry in their mouths for a few weeks before releasing the free-swimming fry.

 Aphyocharax anisits

Kingdom   : Animalia
Class         : Actinopterygii
Order        : Characiformes
Family       : Characidae
Sub-family : Aphyocharacinae
Genus        : Aphyocharax
Species      : anisitsi

Common name :

 Bloodfin tetra
Description :

It is a type of tropical fish. Bloodfin tetras can be recognized because of their colorful fins. The fins of this fish are red in color while the body is silver in color (as the name suggest).

Bloodfin tetras are typically kept in schools of five or more.

They swim mainly in the upper and middle water layers and are highly sociable fishes, mixing well with other types of tetra and tropical fish in general, and so are therefore well suited (like many other tetras) to a community tank. However, they will tend to nip at the fins of fish with long, wavy fins, such as angelfishes or guppies.

 Puntius tetrazona

Kingdom   : Animalia
Class         : Actinopterygii
Order        : Cypriniformes
Family       : Cyprinidae
Genus        : Puntius
Species      : tetrazona

Common name :

Tiger barb, Sumatra barb

Synonym:

Barbus tetrazona, Capoeta tetrazona, Barbodes tetrazona, Capoeta sumatraus 
Description : 
It is a species of tropical freshwater fish. The natural geographic range reportedly extends throughout the Malay Peninsula, Sumatra and Borneo, with unsubstantiated sightings reported in Cambodia. The tiger barb can grow to about 7 centimeters long (2.75 in) and 3 centimeters wide,(1.18 in), although they are often smaller when kept in captivity. The tiger barb is one of over 70 species of barb with commercial importance in the aquarium trade. The tiger barb, an active schooling fish, is usually kept in groups of five or more. They are often aggressive in numbers less than five, and are known fin nippers. Semiaggressive fish form a pecking order in the pack which they may extend to other fish, giving them a reputation for nipping at the fins of other fish, especially if they are wounded or injured. One of the best tankmates for the tiger barb is a clown loach, which will school with the tiger barbs and act as they do, and the tigers act as the loaches do.
