Hi, I have a 52 gallon tank (210L) and dimensions are 100x40x55cm. The tank is densely planted and filtered by an fx4 with 40% weekly water changes. The tank stocking right now is: 1 angelfish, 4 cherry barbs, 7 neon tetra, 5 albino corydoras, 3 mollies, 4 Otocinculus, a Siamese algae eater and a bamboo shrimp.
