I am no expert, but I do pay a lot of attention and have 3 buckets full of pods that allow me to dose my tank with hundreds of pods a month. I have a couple of Bipartitus Leopard Wrasse in my 45g. They only live with a Lawnmower Blenny and 2 Clownfish.
One of the Leopard Wrasse was introduced into the tank with a SUPER long acclimation period of about 5 hours, floating in the tank and dripping simultaneously. He was the size of a Nickel when I got him, which is why I took so long to acclimate him, also for the clownfish to realize what was happening. I got them from a local vendor, not a store, but a supplier that quarantines them before he hands them to me.
At first he ONLY ate pods in the tank. I prepared the tank by over dosing with pods two weeks before, to the point where I depleted 2 of my 3 buckets (like a million in total). It took him about 2 months of picking at the rock while ignoring the other 3 fish eating pellets every morning, but now he eats pellets just as much as the other big fish. He is growing well. You can see a video of him on my instagram @anizatoreef ...or not

I say get them, but just be prepared with backup foods and some pods for sure and keep an eye on their daily behavior. They DO need a deeper-than-regular sand bed 4"+ They sleep in it every evening, so it is their bed. Don't lose your patience. Be a good dad (; Hope this helps.
