Hi giy's anyone know what this is.... one of my oscar's stopped eating the other day and looked a little thin for the past few days and today i found him dead on the bottom of the tank... But something is not right i found a open like soar on him? (See pic)It almost looks like you used a exacto blade and cut a circle through the skin only and peeled it off...what could this be?
THANKS

I have no idea what that is but I am soooo sorry your lost your little fishy

I'm not too sure either, it actually looks very superficial so I'm not sure if this is what caused the death. Have you got a pleco in your tank?

Hi i have 3 small cat fish but i don't think they can do that could they?

looks like a plec or a cat attack / suck to me ..now the boss has mentioned it ...i have not seen this type of wound due to parasites or bacterial infection..only cat or plec attacks/suck,s.......

wow that is extremely odd. I'm gunna hafto agree with the guys and attribute this to the plecos

X2. catfish has slim probability but plecs, yes....
or maybe, that marks happens when he/she is already dead. have
you check the gills?

Hi yes i did they look normal.

so it did not die choking.... but that wound would not be enough to
cause the death. there was an incident wherein plec anchored its mouth
on the side of an oscar. the oscar died because the intestine was sucked
out and taken. but your case is just a cut on the skin.
