I am going to be gone for 5 days. I believe the fish should be fine ill drop a vacation block feeder if I have to but will the plants die with just regular window lighting instead of my t8? I read also that they comptete with fish for oxygen when the light is off so I don't want a crash. I have nobody to take care of it because my sister is getting married down south and we are all going. my dog is coming with me and my parrot is staying at my boys house who doesn't drive
