Cherry shrimp vs. stream pumps
I have a 20 gallon tank with about a dozen cherry shrimp. They seemed content and were all over the place--including swimming about the tank with my guppies. Two days ago I added a small stream pump, and now the shrimp are nowhere to be seen. I have the pump at the top of the tank, angled toward the glass so there is not a direct stream. The plants are happy, but I'm wondering if this is not ideal for my shrimp. I have a larger tank without shrimp, so I could easily move the pump. If anyone has advice about this, that would be great.
