I'm going away for 7 days this is sadly the longest I have had to leave my fish. I have help but only for small things and will not be able to do my regular wc's. Iwas wondering about just not feeding or minimally feeding. I only would expect nitrates would rise a little with normal feeding but I fear my wife will leave uneaten food. Also would like to know what other ray keepers do when on vacation after all summer is around the corner
