Here’s a quick 5-month update on my self-cleaning planted aquarium! 🌿🐟 This tank has become one of the lowest-maintenance setups I’ve ever run. The plants, shrimp, snails, and natural microorganisms all work together to handle the majority of the maintenance tasks for me. That’s the beauty of a well-balanced, semi-Walstad-style system—nature really does the heavy lifting when you set things up right.
My Celestial Pearl Danios are thriving, and they’re definitely breeding because I keep spotting juveniles that I never added! It’s always exciting seeing a tank become self-sustaining like this. I’ve been debating adding more fish soon, but I still can’t settle on a species. Maybe another schooling fish, or something unique that fits the vibe of this setup.
The Helanthium tenellum carpet is growing a lot slower than I expected, mostly because my floating plants have been blocking out a ton of light. I’ll be removing most of the floaters soon so the carpet can finally fill in. My Ludwigia has been dropping some lower leaves, but that’s normal for this plant, especially in lower-light spots. I’ll be trimming and replanting the healthy tops this month to keep it looking full and vibrant.
I also added several houseplants—Peace Lily, Fittonia, Monstera, Arrowhead, and Polka Dot Plant—to grow aquaponically along the rim. Their roots hang into the water and help absorb nutrients, giving the tank an extra natural filtration boost. The shrimp colony is thriving too, though I need to track down some male orange neocaridina because I’m pretty sure my entire colony is female and I’d love to get them breeding.
The hair algae bloom is finally under control after lowering the light and letting the floaters soak up excess nutrients. Water parameters are perfect as well: 0 ammonia, 0 nitrite, and very low nitrate. This tank is truly settling into a stable, self-sustaining ecosystem. 🌱✨
