Anyone ever experience masses or tumor-like growths under the gills of any fish? Or jawfish specifically? I just had a jawfish develop a tumor looking growth that became noticeable when I saw the fish couldn’t completely close its gills on one side and a slight increase in respiratory rate. Had the fish for 1.5 years and was otherwise in perfect health. Also, I am very cautious with adding new fish and have not bought anything new in recent months. Unfortunately, the fish stopped eating on Friday and died this morning. Would obesity cause something like this to develop? This particular specimen was always a pig at feeding time…. And most importantly, is this contagious? All other tankmates are long term captive and acting normally.
