Boesemani behavior

[rjrossi88]

Recently I've been noticing more and more that my rainbows keep swimming into the current made by the waterfall from my filters. Is this normal for them?

They eat fine and swim around like normal and then randomly they all just start swimming straight into the current. I don't know if they're just having fun or what the heck they could be doing.

I wouldn't be too worried if they seem healthy, maybe they just like that current. They live in water with current in the wild, maybe they are replicating that
