Fish Life GraphIf you've ever wondered how your fish are doing, you can use this graph as a tool to see if they're okay.It's very simple; just print the graph out, cut off the extra paper, stick the graph against the tank and line up the bottom of the fish to the center of the half-circle you see below.
If the top of the fish is pointing up, you don't have anything to worry about. Anything else, and there may be a problem.
