Wardley's Slow Sinking Cichlid Crumbles

Does anyone know where I can still buy subject food? It seems to me that
maybe they are not made anymore. I've been buying up all that I could find
over the last few months but finally ran out of on-line sources.

My fish are particular I guess. They really liked Wardley's Crumbles. I've
tried a number of foods they don't like. I finally found another one they
do like... a lot... Kent Platinum CichlidXtreme Sinking Pellets (I use
Medium). Got them from http://www.drsfostersmith.com. Not sure if there is
another source for them.
