I awoke this morning to a terrible sight. my 2 year old green spotted puffer had become curious of the power head inlet. He's become stuck once before during a change over and I was there to save him. But last night he wasn't so lucky. He knocked off the prefilter trying to get a piece of krill. And appearently chased it in.....

He was the size a guppy when I bought him, in fresh water. He was 2.5" now. He was like a cat, very playful, curious, he would eat live goldfish from my fingers.

I removed all power heads from my tank and will be replacing them with two Hydor Korelia 3s.

I feel like my dog died.
