ok that could be the reason and i do blame myself for being a bit too impatient adding too many fish at a time even though i added a new fish about once a week and if i wanted to start over again how should i approach it? if all my fish are going to die and it's starting to look like that do i just wait till they die and then let my tank keep cycling with just hermit crabs and if so when can i add a fish cause my reading's show 0's?
