Live plants are the quiet superheroes of the fish world. They produce oxygen during the day via photosynthesis. It’s like having a bunch of tiny, green factories that never call in sick.
But here’s the kicker: at night, plants actually use oxygen. So don’t think a jungle will save you 24/7. If you have a heavily planted tank and a power outage, your fish might still do the surface-breathing shuffle at 3 AM.
I once added so many plants that my tank looked like a flooded salad. My fish were happy, but I couldn't find my favorite decoration for a week. It’s a good problem to have, as long as you also have an airstone on a timer.
