Fish Trap

I need to remove a fish from the fish tank, specifically, the Strawberry Dottyback.  However, I do not want to have to tear apart my rock work just to catch him.  I decided to build a fish trap to catch him.

It's held in place by a Mag Float.  The peg holds the door open, and once pulled, released the door allowing it to drop.


I made it large enough to catch larger fish.  It's dimensions are 15.5 x 6.5 x 6.  Here is another image with a can of pop inside for size perspective.
