my yellow malawi has got some dark markings around his mouth area whats this all about ?? had them before and it has cleared but its back should I worry ?????
, I presume you mean Electric Yellow?yellow malawi
the bars/markings become more prominent when the fish becomes stressed - either from water quality, or dominance issues. the point is, its natural, and nothing much to worry about.
i'm sorry i wasn't clearer. definitely there's reason to worry over water quality issues. but, black bars due to stress generated from dominance issues are natural. i have had perfectly yellow labs develop and lose bars according to their current position in the social hierarchy.If the fish is stressed, shouldn't there be something to worry about?
Electric yellow colouration is also widely affected by diet and medications. Some processed foods have the ability to turn the fish a muddy colour whilst fish that are fed natural (carotene) colour enhancement food tend to become peach/pale orange in appearance.
is starting to make me think more along the lines of diet rather then water quality being an identifiable issue.Bottom left denotes fish with a lot of black blotchiness throughout the body and “muddy” face mask.
