Lately I have had to spend quite a bit of time out of town and cannot continue to burden people to feed my fish like they thankfully have been doing. Does anyone use good auto feeders they recomend? Also, since I assume auto feeders cannot dispense frozen food is it ok to feed something like spectrum dry for the few days at a time I am away? My fish seem to like this food as well. Thanks for any info you guys may have on this.
