When observing the fish in the water, the fish sometimes stands still and sometimes moves slowly. Inadvertently, time slips away like the fish in the tank. I designed a fish tank like a clock. A small red fish turned into a "pointer" and shuttled back and forth between a few numbers. We couldn't figure out the fish, and we couldn't catch the time.

The idea is full, but I want to ask, is this thing, is the fish alive, how to do it when you look at the time, he is there, if you can't do that, it's just that I put a few numbers at the bottom of my fish tank. And there is no filtration system, either change water or fish frequently.
666. Would it be better to abstract it a little more?
The water is too shallow, the fish dies quickly, implying the passing time
Is it controlled by ultrasonic drive?
this wave is very strong, master Huang
In such shallow water, one jump came out.
This fish tank can be oh!
I can't figure out the fish, but I have to catch the fish excrement.
If mass production occurs, let me know and I want to buy it.
