Passing the, I won't say LFS, as it's more a Pet shop with a few tanks I spotted one tank (no water flow) with about 5 Shrimp in, and quite a few small fish, most of the Shrimp were in a huddle not moving but one was searching the gravel which I've read means it's hungry as they're filter feeders, Atyopsis Moluccensis - Bamboo/Wood Shrimp and seen as I'd a small tank set up with nothing in - Sold ! asking the owner if they sold Liquifry I was asked what for ? to feed the shrimp untill I get an Infusoria culture going was my reply, you don't need that they eat bits of food and Algae pellets off the gravel I tried to explain that they sat on a rock etc. in a water flow and let the food come to them but it fell on deaf ears ??? Got home and rearranged the rocks in the tank to opposite the filter flow, acclimatised the Shrimp and put it in.As soon as it landed on the bottom it was off foraging I dropped a drop of Liqifry in by the filter out flow it climbed the rocks and started feeding then I added a pinhead size Spirulina Powder to tank water in a pipette and squeezed it out just in front of it, it couldn't eat it fast enough. It's exploring the tank at the moment certainly not hiding
and I'm a Shrimp Keeper 
all I need now is to learn the 'funny hand shake' from Odin
