So i finally went and picked up my 220 gal tank today! still not big enough but it will do for now. So the fn guy that had it deff didnt take care of his fish. it was set up for saltwater with a banded shark and some other fish too. He had this tiny little filter on it so im extreamly scared to even test the water. Right now i have it somewhat set up in my basement till i can move all my fish out of my 135 so i can make it the saltwater and the 220 freshwater . So not only did i hopefully save the saltwater fish but i saved two small geckos!!!!!!!!! He said hes been starving them and not giving them water for a while hoping they would die! I was so pist and i asked what he was doing with them and he told me that. so i said ill take them! so hopefully everything will make it. wish me luck!
