    • Fish have been on the earth for more than 450 million years.
    • Fish were well established long before dinosaurs roamed the earth.
    • There are over 25,000 identified species of fish on the earth.
    • It is estimated that there may still be over 15,000 fish species that have not yet been identified.
    • There are more species of fish than all the species of amphibians, reptiles, birds and mammals combined.
    • 40% of all fish species inhabit fresh water, yet less than .01% of the earth's water is fresh water.
    • The spotted climbing perch is able to absorb oxygen from the air and will crawl overland using its strong pectoral fins.
    • Some fish like sharks don't posses an air bladder to help keep them afloat and must either swim continually or rest on the bottom.
    • Some fish make sounds by grating their teeth and others like some catfish make sounds from their air filled swim bladder.
    • Some species of fish can fly (glide) others can skip along the surface and others can even climb rock.
    • Fish have a specialized sense organ called the lateral line which works much like radar and helps them navigate in dark or murky water.
    • The largest fish is the great whale shark which can reach fifty feet in length.
    • The smallest fish is the Philippine goby that is less than 1/3 of an inch when fully grown.
    • Some species of fish have skeletons made only of cartilage.
    • Fish have excellent senses of sight, touch, taste and many possess a good sense of smell and 'hearing'.
    • Fish feel pain and suffer stress just like mammals and birds.
    • Tropical fish are one of the most popular pets in the U.S.
    • 95% of tropical fish mortality results from improper housing and nutrition.
    • Many tropical fish sold in the United States are harvested from the wild in Africa, Asia, and Central and South America.

    And they're all listed in the SA blacklisted fish:bigsmile:.... (sorry I could not resist)

    This is very unique.... a fish that fertilizes her own eggs..... One fish can set you up with a community.

    Strange but true..... Apparently, it is a Killi called "Rivulus Marmotatus".....

    Wow!!!... nothing surprizes me anymore.....
