please also change the water before you go...and do NOT use the feeder blocks...i left to camp for a week and thought they were a good idea...i came home and seeing what the water was like i PANICKED! so either feed before you go probably be fine for a week), or put the "daily pellets" into seperate baggies and say "feed one of these a day) or even only ask the guy to feed them only twice while your gone (portion out the food for them so they wont overfeed). i dont thing that overa week you should worry about feeding them EVERYDAY if someone else (who probably isnt "fish savvy") will be doing the feeding. ask the person watching them for you to feed them like 3 days apart...less chance the water fouls terribly, and has dire consequences. i hope that made sence..ive had a long day.
