Currently my ten gal is on an ancient sponge filter, (which I plan on moving to my new 5 gal tank) I've heard wonderful things about penguin filters and for my 10 gal I was recommended the Penguin Mini bio wheel power filter. I've seen people hanging a 125 penguin off the back of their tank but it seems like a bit of over kill and my fish scare easily enough with a bubbler. Today I took a trip down to my LFS and was about to pick up the mini penguin when a store associate mentioned that the whisper mini was a lot cheaper and would do a very comparable job. Not wanting to get ripped off I figured I'd hike my tail out of their and find out some other peoples comments the whispers is about 8 bucks cheaper but I am willing to dish out a little if the penguin is a superior product.
