My little Otto, Nod, died yesterday. I had never lost a fish and the whole experience was disturbing to me, but I was also surprised to see how much it stressed the other fish. Azul had been chasing the triplets around all over the tank trying to maintain his authority, but since Nod died, he has been going up to the other two everytime they get too quiet and touching them with his mouth just to "nudge" them. The other two Ottos have been very quiet and none of the fish are eating yet. The tank water had been running perfect parameters, but the last couple days I have done 90% changes and still have small amounts of
nitrite, and 30 on the
nitrate scale.
I will miss him and I am sure the other fish do also.
