We had some algae going to town in our 120, and Cloudhands wanted to put some Amanos in to help deal with it. I was afraid that the shrimp would quickly become expensive live food,but when the local fish store had them for $1.99 each, I let Cloudhands put one (of our established, well-quarantined) of our shrimp in the tank. It seemed to do well, and did a great job with the algae,so we added a few more. They are now HUGE, and this evening when the loaches and danios got Hikari algae wafers, one of them was right there in the middle of the scrum, and then started PULLING THE WAFER away from the scrum
We have Kubotai, Striata, Sids, Sumos, Batiks....
Clearly, your mileage may vary, but who'dathunk it?
