sidguppy - napisał, że podstawowe róznice pomiędzy tymi gatunkami nie leżą w wielkości i proporcji ciała tylko:
the difference between the sp 'Jumbo' and the leptosoma is not just size or body proportions.
the best way to see if a certain Cyprichromis (not pavo, zonatus or microlepidotus) is either a Jumbo or a regular leptosoma is to breed it
if the fry has a black and white dorsal fin: jumbo type
if it has yellow dorsal fin: leptosoma
There are no leptosoma with black fins. some do have small black spots or a small black stripe in the dorsal (the Isanga male for example), but the largest part of the dorsal is either white or a lightblue color, often with yellow parts.
many Jumbo type males have a black dorsal with a white edge or a dark dorsal with a black and white band.
females of the true leptosoma have yellowish fins, whereas jumbo females are light brown.
Jumbo females have 2 darker brown spots in the caudal, one in each lobe. the leptosoma female lacks these.
Jumbo females often have a black or dark or black and white band on the edge of the dorsal. leptosoma females lack these.
but the best way to see if it's a Jumbo Cyp or a leptosoma Cyp is the fry.
with fry there's no doubt.
this is also one of the best clues that we're dealing with 2 real species living all mixed up instead of a lot of variety in 1 species.
if you find 2 different types of similar but different fry in 1 location, you can be pretty sure you're dealing with 2 species of closely related fish living sympatric together.
Jak z tego wynika

C. leptosoma ma żółtą płetwę grzbietową
natomiast narybek
Jumbo ma czarno-białą płetwę grzbietową
