I know better

So I broke the cardinal rule of aquarium keeping and let Aquatic Environments talk me in to buying a chalk basslet for my 10 gal nano.
I had never looked at them and upon returning I did my research and found that the min tank size recommended is 20 to 30 gal.
What should I do.
The only other fish going in this tank is a green clown goby. There is about 10# lr in the tank and plenty of room to swim around.
I love the lok of the fish but I don't want to be cruel to him either. What do you think???
And I know I am kicking myself for buying something with out researching it first.

 

Well I got several responses over on nano-reef that things should be ok and at this point the little guy is looking happy, well fed and doing well so I am just going to watch things and hope that he does well. I really like the basslet so all seems to be well.
On another note I noticed that I paid probably twice what I would have online for him at AE and while I would really like to start putting frags in my tank I can't afford their prices for mushrooms and rics. Any other stores in the QC area that I should check out??

 

Unfortunatley the 20L doesn't fit in my office where the tank is located but I am starting to think that my 29 may not get set up for FW after all....hhmmmmm.../site/DesktopModules/NTForums/themes/_default/emoticons/smile.gif

 

Yes I realize that that is true about figuring in shipping and please understand that I am a firm believer that anyone can charge whatever they like. I am the one who paid the money so there is no ill will on my part. My money, my choice. However when I came home and did some research I felt like it was a pretty high price. $10-14 range on internet vs. $27 paid. Again part of why it is important to research what you want. I was just wondering if there were any other places to look.
Also upon rereading my first post I do think that I owe AE a bit of an apology as I think I made them sound pushy. On the contrary I asked them for suggestions and initiated looking for another fish when I found out that they didn't have the clown goby. I resisted his suggestion as to the basslet several times on the grounds of tank size (as I had previously thought basslets were out of my range) and was continually told that he would be ok. That was where I was initially a little frustrated when I got home.
Just wanted to clear that part up. I have bought from AE and will likely continue to /site/DesktopModules/NTForums/themes/_default/emoticons/smile.gif
