I can sense the enthusiasm and the joy you are experiencing over your new pimas all over your text ,and truly you have every reason to be that way ,they are really amaszing fish to keep ,my friend owns a 40 incher in an aquaruim setting i sometimes visit him daily si i can look at that monster , he also avoids feeding the fish anything live, his diet consists most of ,,spirulina mixw/high protein flakes ,,if you do not mind the occasional grab of your hand into his mouth its a joy to hand feed, do nt be afraid they are thoothless but still you can feel some pressure depending on the size of the fish , or you can always use a stick , Hopefully your pond is huge since they do not particularly care for each other company in small settings as they can be fierce fighters/ All the best
