I'm wondering, would my fish be ok for 6 days without food? I have 2 options, either throw in the tetramin holiday food disks, or leave the fish to fast. I don't have timers on my lights so they'd be off for the 6 days too. (Plenty of daylight gets in though). Going to do a big 50% water change the evening before we go and feed them well in the morning. I'm just worried as I have 3 very aggressive yoyo loaches (who I can't catch to rehome) which I fear will attack the other fish if left unfed for too long (we have eyes missing on a few fish). It could potentially be carnage in there on our return. It's two tanks in total (66g community tank, and 40g fancy goldfish tank). Any tips, words of wisdom, advice, or suggestion most welcome.
