Cryptoheros septemfasciatus

Post by ayeo77 » Wed Dec 03, 2014 4:39 pm

Hi all, does this fish ever live along side archocentrus Centrachus? Am guessing they occur in the same river or tributaries of lago nicuragua, esp Rio san juan? But ever together or do they fill the same niche?

They do not compete for the same niche, as the A centrarchus swims much higher in the tank, and is more herbiforous

However, will they ever meet? I don't really know,but as far as I know, C septemfasciatus does have a tiny area where one can find them, only in Costa Rica. If so, A centrarchus, living in Nicaragua and up north, will never meet them in nature

A. centrarchus is present in Costa Rica as well, so the distribution of both species broadly overlaps. However, syntopic occurences (unless "accidental") are unlikely because C. septemfasciatus prefers flowing waters usually found at higher elevations, whereas A. centrarchus typically occurs in the turbid, stagnant and weedy lowermost sections of rivers.
