Sounds like a beautiful tank!! I believe jewels are like kribs and paratilapia species from the Congo river, not the rift lakes and they are right at home in an Amazon tank . This, my friends, is another species that fall under the NW category, as well Asian cichlid varieties. Yes, I know the wide variety of types of cichlids that fall under the category of NW cichlids. Why does everybody have to be so rude?
Oh dear where ever do I begin with this beauty?!
The Congo River is a river in Africa, it's the world's deepest river with measured depths in excess of 220 m (720 ft).It is the second largest river in the world by volume of water discharged. Additionally, its overall length of 4,700 km (2,920 mi) makes it the ninth longest river in the world. It also passes through multiple countries: Angola, Burundi, Cameroon, Central African Republic, Democratic Republic of the Congo, Gabon, Republic of the Congo, Rwanda, Tanzania and Zambia.
While not part of the Rift lakes the tributaries of the Congo do flow in and out of the Rift Valley. With all the tributaries, small lakes associated with the river it's wild inaccurate to say "all these species are from the Congo river".
-Hemichromis guttatus " Common Jewel" are from Ivory Coast to Southern Cameroon.
-Pelvicachromis pulcher "Krib" are from Coastal regions in Nigeria and west-central Cameroon.
- Paratilapia sp. are from Madagascar which isn't even a part of the continent of Africa. They also need water with a ph of 8.0+
All the species listed above which you gave examples of ARE NOT included in the "New World" category. The Kribs and Jewels are from countries in AFRICA! Which means the fall under the order of
"Old World aka African". Paratilapia and any of the cichlids from the Asian continents are more of
"Miscellaneous Ciclhlids".
While the species listed by you do share some of the same water parameters as a South American set up you they are not "right at home in an Amazon tank" mainly do to differences in aggression.
The Term "New World" only includes South American and Central American cichlids.
Also no one is being rude you're just making ignorant statements.
