We have a 75 gallon tank, that we bought used, with all the fish in it. We have a 4-5 inch dogface puffer, a clarkki, a tomato, a cleaner wrasse (I know, he came with the tank) and two diamond gobies. We lost several fish about 3 months ago when we crashed after switching from CC to a DSB. We saved these guys by throwing them into a 29 gal hospital tank and re-cycling the 75. Water parameters are Am 0, No2 0, No3 has spiked from 10 to 60, Ph 8.4, we've been adding buffer. My puffer is now covered in fuzz, looks like he has huge scratches on his back, and his eyes have clouded over. I'm attempting to attach pictures, which aren't great, I'm sorry but he is obviously in really bad shape. The tomato also has this fuzz, everyone else seems fine.
