I bought a cheap glass aquarium for mine. I threw in a heater and power head. Did a 75% water change each week (using the old water from my main display after water change). I'd definitely recommend an observation tank similar to what I did. However if you're starting a brand new tank and ok with the hitchhiker risk involved, don't see anything wrong with just going for it.
Edit: I also don't love the advice that is commonly given to just dip the rock to make all the creatures evacuate the rock. I considered it for a second but came to the conclusion that it's silly to spend all this money and then immediately and drastically disrupt the biome. I'll gamble on the hitchhikers that evade my observation.
