At the ANGFA(Q) meeting last night, which by the way was a beauty, Doug
Collom (Queensland's answer to Alex Caughey) gave us a great talk on
feeding fish and gave us a lot to think about as well as a few laughs and a
few additions to our vocabulary - including an injunction not to
anthropomorphise when considering the diet of our fishes.

One of the most telling aspects was that of temperature, and the effects
that has on the speed of digestion for each species. Another was the water
content of foods - most of our prepared foods are highly concentrated (and
dessicated). hopefully there will be a "Reader's Digest Condensed Book"
version available later in one of ythe club publications :-)
