A small aquarium layout featuring Relax in the Flow, 40L, by Loheac Emilie. The composition is built around River wood.
Read the stone and wood (River wood) as visual pathways before judging the plant mass. The plant list (Eleocharis vivipara) favors a mixed planting; packing the foreground too dense can make the tank feel heavy. backlight substrate helps stabilize root-zone nutrition in the early weeks.
Twinstar 450E lighting sits at a moderate-to-high technical level for this small aquarium. Eden 521 filtration needs enough turnovers without blasting the hardscape; browse matching filters.
