Help!
One of my sailfin mollies is dying. He was fine this morning, and seemed under the weather but ok earlier. Now on the bottom giving up!
Nitrate/nitrite levels are near nil, carbonate hardness fine, ph 7. All other fish are ok (except 4 minnow have lost an eye each?).
What could be the cause? I wondered if perhaps a lack of oxygen, as the filter has been running under power due to nitrate pouch almost sealing itself inside the filter and causing the water flow to slow.
