Tank Planner

Build your tank, species by species.

Pick the tank, pick the filter, then add the fish, plants, shrimp, and mosses you're considering. We cross-reference every parameter, check stocking against best-practice rules, and tell you what light, CO₂, and substrate the combined tank actually needs.

Tip

Ember Tetra schools, stock at least 8

You've planned for 1 ember tetra. Ember Tetra need a group of at least 8 to feel safe and shoal naturally, below that they're stressed and lose colour. Dial up the count, or remove the species.
