Also is was to my unfortanate, that i discoverd my pirhanas extramly sick, one was dead, the other two are half floating around sinking, not moving only breathing, i put melafix in that tank to. as far as the pirhanas i got some live plants about 2 days ago from a friends and not hacing any were to put them i just put them in the pirhana tank which is a 10g. the pirhanas are really small about 2/3 inch each, they semmes ot like it but, today i dont think it was too good for them. any suggestions what should i do, i am losing all my fish.
