Hi everyone! I'm leaving the house for 2 whole days. I have two aquariums: 1) 23 Gallon (with thick substrate, rocks and fake plants) - Harlequin Rasbora - Cardinal Tetra - Rummy Nose Tetra - Octocinclus - Sterbai Corydoras - Red Platy - Betta 2) 2.6 Gallon (no substrate, just one gish hideout) - Red Platy Fry (1 week old) How long can I leave these tanks without food? I'm a bit concerned with the 2.6g fry tank as they might die from hunger. Would it be okay if I left a Hikari Algae Waffle at the bottom of the tank so they can munch on it? Or should I just leave crushed food floating on the water surface? Will they be able to survive? Will my community tank be okay as well?
