John your setup sounds fantastic mate!
Same as you I feed mine a varied diet and they eat anything that goes in.
I would avoid an auto feeder, they can go wrong and throw it all in at once and do the water quality serious damage
I've heard so many horror stories with them going wrong overfeeding or not feeding at all.
I'd avoid auto feeders at all costs mate.
Would love to see some pic's of your setup mate, I'm, drooling over the sheer size of it already!
Ps. Never fed mine tinned sausages in brine, but for less then 25p I'll give it a go
