Nice picture. I bought 4 Ghost shrimps for my big tank. They were sold as feeder shrimps at 33 cents each. I like them as they add interest to a tank. I have Red cherry shrimps in another tank. Ghost shrimps are a good shrimp to get to start out as they are cheaper and if they do well you can get the more expensive Cherry shrimps. Here's a picture of my Red Cherry shrimps.
Yes thats what I was thinking when I got them if I do well with them I may get some like the ones you have or I also saw a yellow version on ebay that I really liked but they were a little more expensive than the red cherrys. I thought they would be boring but I am loveing them as much as I love the fish to. There is one that is bigger than the rest and when I feed the fish he swims up to the top of the tank and swims upside down to get the flakes instead of waiting on them to float to the bottom. I call him Bubba. LOL
