Food and feeding habits of T. zillii were studied from fish samples collected from April to May (dry season) and July to August (wet season) from Lake Ziway. Stomach content analysis was conducted using frequency of occurrence and volumetric methods of analyses. Macrophytes, detritus and phytoplankton were the dominant food categories occurring in %, % and % of the.

Autobiography of Rev. Abel C. Thomas
The redbelly tilapia (Coptodon zillii, syn. Tilapia zillii), also known as the Zille's redbreast tilapia or St. Peter's fish (a name also used for other tilapia in Israel), is a species of fish in the cichlid family.
This fish is found widely in fresh and brackish waters in the northern half of Africa and the Middle East. Elsewhere in Africa, Asia, Australia and North America, it has been Class: Actinopterygii. Redbelly tilapia is a species of fish that has been introduced globally, mainly for aquaculture purposes or as a food fish.
Native to Africa and southwest Asia, it is a highly successful species, capable of outcompeting both native and non-native species for food, habitat and spawning sites.

Another popular aquarium fish of this group is the angelfish, or scalare (Pterophyllum). A notable cichlid is Tilapia mossambica, a prolific African species that is now cultivated in many regions as a source of food.
Tilapia zillii is used for aquaculture, commercial aquarium trade, a weed control agent, and as a recreational fishery for many countries through out the world (FishBase, ). In a study investigating the feeding preferences of T. zillii among four species of aquatic plants, it was determined that Chara sp.
and Najas marina could be controlled by T. zillii in small lakes and ponds (Saeed, ). Tilapia is a genus of cichlid fishes endemic to freshwater habitats in Southern the past this was a very large genus including all species with the common name tilapia, but today the vast majority are placed in other genera.
Species and taxonomy. In the past, Oreochromis and Sarotherodon were retained in the genus Tilapia, but these are treated as separate genera by all recent Class: Actinopterygii. The Butterikoferi Cichlid, also known as the Zebra Tilapia, inhabits the river systems of Western Africa.
The coloration of this fish is a series of black and white vertical stripes. Although they can be peaceful when young, as they grow so does their disposition, which becomes very territorial.
Difficult to distinguish reliably from Coptodon rendalli, but C. zillii can have a less-steep head profile and more prominent vertical bars; in East Africa, the tailfin of C. rendalli is often divided into a brown/grey upper part and red/yellowish lower part, whereas the tail.

Redbelly tilapia is similar to another North American introduced cichlid, spotted tilapia: spotted tilapia lacks the deep red ventral coloration present in T. zillii, has lateral bars that extend onto the dorsal fin, and square black blotches along the side (lacking in T.

he is a veritable giant among ichthyologists and has had more fish named after him than I've had fish suppers. His great book on cichlids is THE work to go to for identifying any cichlid that you might find in a fish shop/5.
This was the first cichlid book I read. It was recommended to me and I'm so thankful for that. It tells you everything you need in order to start up a successful cichlid tank. And I'm not talking information like all the other fish books out there that tell you how to setup a tank with all of their products/5(16).

Sounds like a good idea to put him in a hospital tank so he gets some peace if they indeed fought altough a 5 gal sounds small.
I would consider getting something bigger.

Cichlid fishes are famous for large, diverse and replicated adaptive radiations in the Great Lakes of East Africa.
To understand the molecular mechanisms underlying cichlid phenotypic diversity Cited by:. Analysis involved two strains of T. zillii: strain 'A' (T. zillii) and strain 'B' (formerly known as Tilapia tholloni). Spawning periodicity and total fecundity generally increased with fish size.
Egg size varied within a narrow window and did not generally increase with fish size though fish weighing - g tended to produce the largest by: 1.Tilapia buttikoferi need to be kept in an aquarium of at least 75 gallons.
They are fairly easy to keep but do require large, regular water changes as they are high waste producers. The Zebra Cichlid may be aggressive to smaller tank mates, always keep this fish with similar sized know as Buttikoferi.
Tilapia zillii Gervais is recorded for the first time from Suez Bay off the Institute of Oceanography and Fisheries, Ataqa (UAR), during October and November and Salinities and temperatures of surface sea water ranged from 42 to ‰ and 23° to °C, respectively.
The occurrence of specimens of T. zillii in the Bay indicates that it can tolerate high salinities and survive Cited by:
