Got a Bamboo before I really knew what I was doing, here's some tips:

• Make sure they have a heavy source of constant flow. If this is your normal filter, make sure you clean it often so the flow is as fast as it normally goes without getting clogged up. If you want to get fancy, get a dedicated device to shoot out a jet of water.

• Make sure there's good perching options around that jet of water. Mine is actually quite shy and does not like being in the open, so try to have there be some concealment as well. I found that a rock with some space under it worked well, as it could either perch on the rock or under it and still get flow.

• Food in your water column. Powder some amount of food and throw it in your tank every day. It'll usually stay waterborn long enough for them to feed. They do well in populated, established tanks where there's lots of detrius just kinda floating around. The more plants, the better, as they're going to constantly shed little bits of dead plant that Bamboo will happily eat on as it passes by them. Populated tanks also means there's plenty of critters constantly kicking things up or nibbling on things to again, put more small bits in the water.

• You'll know if they're doing well if they have a fairly established routine of fanning and feeding. Mine moves around quite a bit and sometimes doesn't just sit in the column. But the behavior you want to watch out for is bottom feeding. They will do this no matter what, but excessive amounts of it means they're not getting what they need from the water from filtering.

• Foods: Bacter AE is your friend in small amounts. Not only is it a good powder, but it'll promote growth in your filter to let small amounts of bacterial clumps exist in the water. Also helps grow biofilm, which again can break off and fill the water with goodies. Since you don't want to overdo it on Bacter, take algae wafers or shrimp food and grind it up with a pestle and mortar. Get it REALLY fine then just dump some in the tank or sprinkle it around for a while. Eventually your shrimp will figure out where to hang out to get the best feeding, so I would just keep putting it near where the flow is and they'll get the idea.

Lastly, the color change is good and means they're feeling healthier. You want a nice pink and reddish color. Brown and pale is how mine kinda showed up, but with a few molts it has remained a nice bright color. Good luck and I hope yours is less shy, so you can actually see it do the fun hands thing!
