I was saddened to see my oldest fish (except the 10+ year old clown that was donated to me) passed last night. Jammies, the pajama cardinal came as a full grown fish some time in 2018. I knew he was declining because he got a bacterial infection several months ago in one eye. I treated it with antibiotics in a hospital tank and it seemed to look less red, although it remained popped looking. He ate well even yesterday but I had noticed his fins getting ragged so figured he was still declining. I am sad to lose him but he lived out a pretty normal lifespan for a pajama cardinal from what I have read.
