I have a few laying around and am debating if I should put them in the tank or not. What are the benefits/drawbacks of them. I am assuming it will make them more active (which I am in between on if I see that as a good thing or not).
I have one in my Rhom tank. He seems to enjoy the current at times. I'm thinking about getting a stronger one, as I'm just using a small one I had lying around.
