The name for the Common Pleco, Liposarcus Pardalis, has definitely changed. I was told on a specialised forum. I was even told how to pronounce the new name (still can't though, it's just too long a word).
Are you serious!? I would hate to live with you or anywhere near you if that's the kind of stuff that bugs you. Grow up! It needs to be done for cichlids and many other kinds of fish considering the common names are generalizations and can be used for more than one fish... example being the word "zebra" being used with any color in front of it...
I think it is fine using latin names to ifdentify a species exactly. I do the same with parrots. Personally I find it annoying when I am expected to 'dumb down' simplybecause someone doesn't understand what I'm talking about.
I don't find it a massive problem doing a google on a latin name. It simply means that I have learned something.
see my sig'.
