Will they order what you are interested in? If so, I think you are way better off. i like to see what I buy before I buy.... I am a price who$e on some things, but livestock is not one of them. I want to pay a fair price, but I want HEALTHY fish.... And on the Hippo, if you start with a small one and start an exit plan, you should be fine for up to a year. I have 2 in my display. I know there are always people interested in them at fair prices on ARC. Good Luck with the new tank.
There are lots of knowlegable reefers on here. If you ask the questions you will get lots of great info. Sometimes 3 or 4 oposing answers, but always good answers.
