The aquarium engine is designed to run on all devices from the
very small (mobile) to much more powerful devices, including PC.
Fish and object models, as well as all textures, obviously need
to be adjusted for the target platform but the AI engine behind
it all provides a convincing emulation of fish behaviour on all
platforms.
Fish can feed, grow, breed, become ill, interact with other fish,
including displaying shoaling behaviour, interact with the environment,
swimming in and out of moving plants and ornaments, and interact
with the game player, for instance, coming to investigate when
the player chooses to tap on the glass of the tank.
