I have had them since December, they are doing just fine and eat very well. I do target feed them daily. The larger fish are just too fast for them.
I watch them a lot, they are probably the most interesting fish in my tank. They constantly pick the sand I assume in search of
pods.
When I clean out my polyfilter, I always have a dozen or so
pods caught in it. I gather them up and drop them back in the tank. My scooters are all over them in a matter of second.
So far no problem with them. I didn't know until after I purchased them, all the problem associated with them. So I probably give them more attention because of this. Actually I think I have a male and a female. They are always together and the larger one lately is "showing off" to the smaller. He will jump in front of her and flare up his fins doing a little "dance". I assume this is a courtship ritual.
I just order this on ebay.

With the hopes of beefing up my pod population some more. Am also going to evict one of my sand sifting stars to help keep the pod population up.
Great fish, I really enjoy them.
But I would not suggest them for someone unless they are commited to properly care for them and have a large enough tank with a good pod population.
Here is a pic of the larger (male I think).
