I spent a lot of time recently debating this in-store. I went with the eclipse simply because I heard the filtration (and Bio-Wheel) were great. I really like it - I got the Corner 5 - and it fits perfectly on my desk here in my dorm (and I can see the entire aquarium). I also liked how it looked much better than the Minibow, but that's just personal preference.
One qualm I have though is the aforementioned filtration. My male betta doesn't seem to like it much, and spends more time hiding away from the current. When I turned off the filter earlier, he was zooming around and having fun. Obviously I don't want to turn the filter off completely, because I love WHAT it does. So how does one "buffer" it, to perhaps make the flow lighter?
Thanks! And good luck with your decision!
