UNS 45L low-tech iwagumi, no CO2. Planted with monte carlo and a "moss ball" torn up to decorate the seiryu stone. It was dry-started in January 2025, and has grown in a little bit but not as quickly as I'd like it. Stocked with 7 medaka rice fish, a massive amount of ramshorns, and 5 orange neocaridinas (which are showing cherries now). I have done only 1 water change on it since leaving the dry start, and weirdly has zero algae and is the least demanding tank I have.
The vastly oversized filter you see doesn't have filter media, but instead houses several terrestrial plants including some pothos (marble queen), some ficus variety, and a variegated syngonium. I picked a giant filter (made for 15 gallon setups) in order to create a "sump" to increase the water volume in the overall ecosystem to ensure everything stays stable.
Aww that's beautiful. I just got medaka for my indoor pond (and orange neocaridinas and ramshorns too lol) and they are such lovely fish. The stonework plus greenery is so artistic!
Thank you so much ☺️. I have really grown to love medaka and want to make an indoor pond with them as well. How is yours looking?
