Hey everyone. I recently posted about fish dying off one by one with really no signs of disease. Water parameters were great.. I lost 7 fish in a matter of two weeks. The last fish died about two weeks ago. seven fish survived. One of the survivors didnt eat for a week and recently started eating again. He is also not as shy as he was previously. I have 8 fish in quarantine in a 10g they have been in there for a couple months as I didn't want to add them to the 75g where the fish were dying. How long should i wait to be sure the 75g is safe to add the new fish. Was never able to diagnose what was killing the fish. The remaining seven all seem normal and eat well. Any ideas? Thank you so much everyone.
