I've always fed my fish if I went away..well someone else lol. Never had a big problem but always came back to more algea or something. One week gone by with me not the algea swing though. No one will be around to feed them either so I'm try my luck at no feeding. Def appreciate the tips. Still a bit nervous of 7-8 days of no attention but ive read what you all have said about they should be fine. Feel like I'm gonna be worried about them like If they were my kids lol
