since the lateral line is a sensory organ, working via vibration similar to our inner ear, then it 'sounds' (sic) logical that the line would be more visible if the fish were stressed. answers #1, #2, and #4 are excusable, IMHO. post a pic? HTH.
yes. but variants like moba, get so dark overall when stressed, it might be less obvious to see.gpb210 said:Will this sensory dark line be found in Moba or other gibberosa?
**yes...i would say it is more common to see lateral line exposure with juveniles of burundi type than compared to zaire variants. but do not assume the condition to be a negative one. it is better described as a sign of awareness or attentiveness. perhaps burundi types are more inquisitive? or more likely...they simply have bigger 'ears' than their southern cousins.gpb210 said:So might i say that the heavy dark lateral line is a feature of burundi, espically for those pond raised and under stress. For other fronts/gibs, no such obvious line can be seen except for those variants.
