This simulator renders in 3D. The static diagram behind this message shows the same concept, and the parameter panel still works.

How to use it

Set the tank size and water parameters first — everything is scored against those.
Add species from the library. Each addition re-scores the whole list.
Watch the 3D shoal. Territorial species establish and defend a corner; shoalers group.
Read the compatibility report: water match, size match, temperament and territory.
Adjust quantities and watch the crowding and stress index respond.
Export the final stocking list with the warnings attached.
