I keep a few ghost shrimp with my Pleurodeles waltl (sub-adult). The shrimp may 'gambol' around the tank like apparent lambs to the slaughter....

......but they prove MUCH too fast for "Mr Pleurodeles 'McFatWorm-withCheese' Waltl" if they consider themselves to be on the menu.
I'd say that the shrimp would be quite good in terms of their nutrition/digestibilty.....I would be inclined to say that they have a decent Calcium content also and can be 'gut-fed' with nutrition easily.
I remember from a previous thread about the differences in prices of ghost shrimp (Palaemonetes?) between the UK and the USA. They tend to go for 4 shrimp/£10 in my LFS in the UK....$3.50 per shrimp?
With this species the breeding conditions need to be brackish/estuary conditions, I believe, which would be challenging to recreate.
Red cherry shrimp however, can breed in freshwater very easily given favourable conditions......
