I have had great success with my dwarf shrimp over these past few months. When I moved this aquarium into the new location a few months ago, I barely had any shrimp. To my surprise, they seem to have been breeding regularly and the colony has grown. The aquarium consists of crystal red shrimp, crystal black shrimp, and a couple orange eye blue tigers.
I plan to set up a shrimp rack within the next few weeks and will start separating the shrimp and focusing on getting higher quality grades. Here is a video of the shrimp aquarium after a small water change. The shrimp always seem to be so active every time I do one.
