Yup- I'll add in a vote that they are excellent tank mates right through the axie life cycle- I've got 10 of the closely related red cherries in with some of my larvae at the moment (Ones who didn't want to come out of the hatching tank), and the baby shrimp are acting as a pretty good food source, and the adults are an excellent cleanup crew. For my adults (In the last tank build- I reestablished the colony during the current tank layout, and I'll be re-adding them to my next one) they are gorgeous- something to play with, pretty good nutritionally and assist in keeping the tank clean
. One thing I'd suggest is establishing a separate shrimp tank- that way you've got a population on hand and even if your axies get all the ones in your main tank, you won't have to start from scratch again
