I’m leaving from Friday night to Wednesday. I should I do water changes Friday morning? I have 6 tanks one of which is a fry tank. I have 2 automatic feeders and one is going on the fry tank. I have a betta tank, and tank with tetras mostly, and tank with tetras and an angel, a South American cichlid tank and an African cichlid tank. Which tank should I put the automatic feeder on? Also, do I need to feed my other fish? I can have someone feed them if I portion out what they should feed and it would be once every other day. Also, I have 2 planted tanks that don’t have timers and one that does. What do I do about the lights?
