Just felt like sharing this. I have 4 harlequin rasboras in my 29 gallon tank and the filter outflow is a little strong for them when they swim directly under it. Yesterday I was watching them and I saw all 4 rasboras, swimming in a group, swim through the filter outflow and get blown around a little, and then they all turned around at once and swam back through it again with the same result. They did this continuously for almost 2 minutes! It was so funny! It's their own little waterpark. Has anyone else seen something like this?
