Solar Powered Robotic Fish in Aqua Substance
I love fish, yet don't like the fact that I have to clean the tank, feed the fish, and such. I would love a robotic fish tank that would easily be charged, and the fish would resemble tropical fish. It would be great if this tank would not can water, yet another substance that would prevent spilling. It would run on solar power. Possibly could train the fish as well.
