Not my favorite, but the coolest would be my tiger goby. He is an Atlantic species that came in as a LR hitchiker, and is only about 1' long. He's so small that it only took about 1 week before he ended up going over the overflow and ended up in the filter sock.
I initially fished him out and put him back in the tank, but he kept going over the overflow. Finally I decided WTH, I'll just keep you in the filter sock.
He has been there for about 8 months now, and every time I change the sock he just goes into the new one. I think he just eats all the pods and stuff that collect there. Seems to be pretty happy, too! So now he's the official Filter Sock Fish!
