I clenaed my tank today, it was really gross because the filter had clogged up with plant. Anyways, i changed the water, i know they need bacteria but the tank was really dirty. Now one of my fish has died and now im worried that my other fish will too. It was a cleaner fish that died, i have goldfish and comet goldfish. How can i make sure they wil be fine?
My two oldest fish would be used to complete water changes as i used to do this when thy were in a small tank.
