I have made my final addition to the tank, a large 6.5" Blue Turqouise from what i can tell at least, huge fish, bit tatty as he hasnt been getting looked after right but i shall see him right, pics below
Im assuming its a he because of the nuchal nump on his head and he seems to be interested in the 2 discus that are female.. or at least i suspect to be female, he is a lovely fish, shame he hasnt been looked after right, his fins are all raggedy and he had a bit of cloudy eye too, but he gets more coloured each day so far
