yup, like in Elite's sig - the book I've got calls them Ramirez' Dwarf Cichlids - I'm not arguing, just what I read
They are my fave too, great characters, very lively and have an occasional habit of rubbing their sides on some smooth rock I have in the tank (don't ask me)
My Tiger Barbs are cool too except one of them who won't swim with the other four (odd) - (s)he isn't even the smallest either.
