I'm desperate for some help with this puffer! I think I"m going to loose him. I got him last week, and the next day after I got him he blew up in the tank for no reason. couple days later we moved the tank (stress maybe) then we got a foxface rabbitfish as a present. So we put the rabbit in there. They seemed to get a long just fine. But, now he has a huge white discoloration on his right side that is getting worse. It covers his whole right side now and is swollen, he's loosing the skin by his spikes. You can see the clear spike in him. It is not fuzzy and sticking out. It looks wrinkly just discolored. His fins and eyes are clear with no cloudiness or spots. He was eating up until yesterday. He's up at the top of the tank all the time. The pH was low last week at 7.8 but now it's up to 8.2. Ammonia was around 0.25 but with tank changes I got it down. Nitrites are fine. temp 79-80. I'm at a loss. I wonder if the rabbit stuck him with his venom?..
