FishTank Fun

This interactive Fish Tank Aquarium is a full-screen animated ecosystem where you control the life inside the tank using sliders and buttons. You can add and adjust populations of fish, rainbow fish, orange/black fish, mini sharks, octopus (which periodically squirts ink clouds that obscure the water), jellyfish with tentacles, crabs and lobsters on the bottom, algae eaters, seaweed, and tall sea leaves that sway with stronger current. The tank includes environmental systems like algae buildup in the corners that algae eaters clean, feeding behavior where a Feed button drops pellets from the top and fish swim to eat them while some sink to the bottom, and predatory behavior where sharks chase smaller fish. Visual modes include fullscreen cinematic view that hides the control panel and a night mode with colored lighting and darker water. Additional animated elements include bubbles, ink clouds, plant motion, sand floor with pebbles, and real-time FPS display, creating a dynamic, living aquarium simulation.
