Any of y'all have them? I read on a different site that quite a few loach owners have powerheads just to create more current for their loaches to play in. Since loaches come from fast-flowing streams and stuff. I was thinking about getting one in a little while. I already have two filters running in the 10-gallon, which was a fluke, but the loaches seem to like it. And I've noticed with the loaches that they "gather" where I pour in the water during water changes. They play and dive in the powerful current of water coming from the bucket. I'd like to see that more often.
