Naw, perhaps a little time consuming. Mainly you want to make sure they do not starve. Some people just throw them into the tank and never really think about them again, but they have some specific needs, and imho you need to feed them in a way they can be sure to be fed.
Being in a tank they can't just wander over to a new place to feed like in the wild, so we need to make sure they are taken care of. If you feed heavily already, as in an over feeder, you will probably not need to feed specially 2x per week, but change way more water.
If you can see them in time growing, and daily sitting in the flow filtering with their fans out then they are probably getting something from the water column. Maybe I worry too much,
But they love getting the fine particle food, then after a few hours you do a pwc, rinse the filter pad (only with treated water of course) which just captured a bunch of uneaten food.
Sometimes these guys will wander the floor of the tank to mop up some food on the way to another place to perch, but if they are wandering the floor of the tank mopping often you know they are needing food, because it is not a normal way for them to feed.
Frequently people who get these shrimp say that theirs only lived 3-6 months, and I believe often it is because they are not fed well and starve. If they die in a month or so, it could be from a tank whch may not be cycled or they were not well in the first place.
If you go and purchase one or a few, try not to get the very largest ones 4-5 inches are going to be the oldest adults. ~3" is a good size. But if you get a really large one just know that it is older and may not be as long lives in your tank.
They are a really fun shrimp to keep.
Here is a pic of one I got, a larger sized one when first purchased he was tan and very pale, this is just after his acclimation and being dropped in. An hour later he was the color of the bottom pic.
This is after being in the tank a couple months, he liked this spot as it had a narrow space making it a high floway, and his other spot on top of the DW in front of the inflow. See he looks bigger and stronger.
