My tank has just went under tremendous stress and my fish have ich (or fin rot). They are all at the top of the tank. Does this mean theres not enough oxygen? How can I help them? Thanks
I just added new water... as my heater went haywire and raised the temp. I had the water checked and all levels were fine... despite a slightly low ph. Im just wondering if it could be the stress, or if they are not getting enough oxygen from the medicine. thanks for your reply!
