submarine for fish tank?

So I just saw information about this moai automatic glass cleaner: https://www.kickstarter.com/projects/moai/moai-robot-for-your-aquarium

This got me thinking; is there a worthwhile little submarine you could stroll around the tank like a drone and get video/pictures/find missing anemones etc in rock work?

I don't think you'll find a model submarine small enough for your tank. How about a water proof camera on a stick instead? That should get your rockwork inspections done.

I've thought of that, just thought would be really cool to control one like a drone and swim around the aquarium.
