Wanted to share my story with others to give some a laugh and to push the importance of cleaning your tank! Lost my Yellow Watchmen Goby about a week after buying it, hadn't seen it in over a week and I just recently scrubbed some Algaee and it layered my filter sock, So I wanted to pull it and clean it out. pushed the sock thru itself and turned it inside out to spray it out in my sink, and guess who shot out like a fish out of water (QUITE LITERALLY). So ******* excited thought a $60.00 fish vanished out of thin air and he survived living in a waterfall for over a week. Not to mention that he squeezed thru a 0.14-IN hole that I drilled in my DIY aquarium overflow, went all the way down, and back up through the biggest waterslide of his life. Just goes to show cleaning and husbandry really do reward.
