Sad to say but about a week & half ago I lost my porcupine puffer, I was sitting in the kitchen when I heard my pumps making a loud sucking noise I ran in only to discover that my one overflow stopped siphoning and that my tank was about to overflow, only one overflow could not keep up. To make a long story short my puffer got into my overflow and was sucked up and was stuck in the pipe, I had to cut the pipe to get him out little did I know that he was right where I was cutting and I cut his tail off but he was still a live I put him into another tank but died a few days later. The problem has been fixed where the fish can't get into the overflow and I plan on getting another puffer.
