In my tank, I have two guppies. One adult, one baby. The adult guppy.. lol... swims around with my mollies all the time like she's one of them.. or trying to be in their cool group. But then... for what seems like hours, she will go to the top of the tank and swim straight in the current of the filter, and if she gets off course, she hops right back in. I mean seriously, hours on end. It's really funny!! I think she's in training.

Our kuhli loaches are forever getting into the filter outflow, swimming against the current upwards. We've had to cover the holes as we heard they could behead themselves that way!
