i,m thinking about buying 3 bamboo shrimp for my planted tank and i would to know how to take care of them. i know they are filter feeders and i,m going to put two thick clumps of lucky bamboo on each side of my filter with just enough room for the filter outlet to be unobstructed so they can hang out on the plant they were named after while picking the tasty bits out of the strong current. i just want to know the details on keeping them happily fed and cared for,how much calcium do they prefer in the water? etc. thanks
