I had a bad bad experience durring my weekly water change i made a huge mistake i dumped a bucket of non mixed un chlorinated water into my tank i realized my mistake. And saved the fish with a quick qt set up but i was unable to get all my corals out needless to say i ran to the store to by tap water safe stuff and when i got back everything was dead im devistated but coming back i have since recycled my tank and put my fish back in their new old home. But i noticed these guys when cleaning what are they ???
