you can have accurate common names but there needs to be a different common name for each. Don't get me wrong, i am "pro latin names" but i also realise that others do not share the same passion or have hours & hours to search through various sites researching latin names etc. i am not familiar with new world cichilds but alot of african common names are their latin name which helps but there are also many common names, different for each fish including similar fish like peacocks.
