Hey folks, I'm pretty much new to the forum. Hopefully someone can give me some insight into a problem I encountered last night. I have a 55 gallon corner tank fully stocked with lots of fish. Because of my high population it's pretty important for me to be running all the requisite "water movers" (skimmer, fluval filter, powerhead etc). Anyway, I brought home a dog puffer aprox 3 inches in size. It integrated quickly and without incident. However, 12 hours into his first day to my horror, I found him sucked into the powerhead’s intake and puffed to the size of a grapefruit. I have not had this problem before with other fish, but this is my first puffer and I'm attributing this incident to his bulbous size. Has anyone had this problem or heard of it? I've got to keep my powerhead running, but right now it's turned off. Your suggestions would be much appreciated! BTW, the powerhead is an "aqua clear" 70. Cheers
