Last night I finally found a store with ghost shrimp.. 10 cents a piece, couldnt pass them up so I bought 4.. well 3 actually but I guess the 4th one deciced to jump into the net, so I got him for free. How long do these little buggers last? they are very interesting to watch. Was funny my betta fish got curious and was pokin his nose at him, then a shrimp kinda jumped up and smacked his nose, then the betta left him alone.
