I have a 29 gallon tank set up with 6 hillstream loaches, 9 tetras and 10 blue eyed rainbow fish. I’ve been using the repashy soilent green for my loaches and there’s usually some leftover but I’ve been leaving it in the tank because I know they like to graze. I’ve noticed that my tetras and rainbow fish will also graze on it throughout the day. Should I still feed them their own food even if they’ve been grazing? I don’t want to over feed.
