Lay out stone, wood and plants in a tank drawn to scale. TankHaven checks that your fish, shrimp and plants can live together, then works out what to buy and what order to do it in. Freshwater planted tanks and saltwater reefs.

One betta in a heated, filtered 5 gallon with slow-growing plants that never need CO₂. Small, quiet and very easy.
Tangled wood, broad swords and floating cover over a school of cardinal tetras and a group of corydoras. Tea-stained and calm.
Terraced rows of red and green stem plants in the Dutch style, with harlequin rasboras and a clean-up crew. High-tech, with CO₂.
A long tank with room to swim: boesemani rainbowfish and congo tetras over swords, crypts and tall background stems.
Six feet of river-bank planting: onion plants and temple plant at the back, swords in the middle, and schools of fish to fill it.
