Designing Aquarium Builds That Show Off Boids Movement

Design Around the Three Rules

Every design choice should support Separation, Alignment, and Cohesion. Separation keeps fish from stacking, Alignment makes them move as one, and Cohesion holds the group together. Builds that fight these rules look static; builds that support them look alive.

Layout Tips

1. Favor rounded or open footprints. Corners trap Cohesion and cause fish to pile up. Circular or oval pools let the school flow continuously.

2. Keep the center clear. Put coral, rocks, and plants around the perimeter so the flock has an open volume to swim through.

3. Use depth, not just width. A tank that is deep as well as wide gives the school vertical room, and you will see fish align in three dimensions rather than sliding along a flat plane.

4. Control lighting and glass. Viewing windows placed at the level where the school tends to drift make the movement readable; a fully enclosed tank hides the effect.

5. Size the tank to your stock. A small school in a huge tank disperses; a large school in a small tank crowds and jitters. Match them.

That synchronized turn is the signature of the boids simulation and the thing worth capturing.
