Nano Question?

[rbaby]

I went to a different local fish store today and inquired about Protein Skimmers. I have a 12 gallon eclipse tank and with the hood it's just nearly impossible to get a skimmer without having to cut up a hole for it.
The gentleman who helped me alarmed me by saying that my fish and tank will die if I don't get one :nervous: . I hear many of you successfully having corals and fish in your nano's and I just wanted to know if this was true? Help? I'm freaking out~!

He suggested that I get a new tank altogether...

I have a 10 gallon Reef tank that is doing just fine with a Millinium hang on filter,and a powerhead. I have 2 Percs,4 corals and a clean up crew.
Calm down!......You don't need a skimmer.
If you go to fish photography in this forum look at Nano 7 pack.
That's my tank.
