I've been reading many comments from people talking about freshwater shrimp. What's the fascination? Are they friendly? What do they do? Are they fun to watch? Do they co-exist well with fish and what kinds? Are they big or small? I have to know.
I agree. I always thought of them as fish food or clean up crew. Then I added some RCS to a new nano tank I set up just over a year ago. It really is fascinating to watch their interactions and how the social hierarchy has developed. I actually have 3 distinct colonies in my tank. The 2 colonies in the front do mix at feeding time and then go back to their own areas. The third colony lives in the filter compartment. A lot of people have gone to great lengths to stop this on that type of tank (Fluval Flex). I just let them have their own way and one group has chosen to live in there.I have a tank of Red Cherry Shrimp. No fish. Yes, they are fascinating to watch. I can sit in front of the tank for an hour watching them. Adults can be about an inch long.
