$('.post-button').on('click',function(e){
    var new_fish = $('<div class="fishhatch" ></div>').insertAfter($('#rightarrow'));
    animatenewfish(new_fish);
});

function animatenewfish(fish) {
    var Fishv1 = fish,
    theContainer = $("#container"),
    maxLeft = theContainer.width() - Fishv1.width()-100,
    maxTop = theContainer.height() - Fishv1.height()-100,
    leftPos = Math.floor(Math.random() * maxLeft),
    topPos = Math.floor(Math.random() * maxTop)+100,
    imgRight = "Assets/R1gif.gif",
    imgLeft = "Assets/FIsh1.gif";

    if (Fishv1.position().left < leftPos) {
        Fishv1.css("background-image",'url("' + imgRight + '")');
    }
    else {
        Fishv1.css("background-image",'url("' + imgLeft + '")');
    }

    Fishv1.animate({
        "left": leftPos,
        "top": topPos
    }, 18000, function(){animatenewfish(Fishv1)});
}
