The southern PAH in lincoln has 6 inch shovelnoses, 6 inch alleycats, and syndontis, and also has a plec labelled L171 which is not an L171. They always have fish like these and they are all in the standard centralised tiny fish display tanks. They also have loads of CAE labelled 'Sucker Fish' and like you say the specials never seem to have a proper label. Its always just a blue paper label with black laser print with the name and price.
