I was wondering if anyone know's what's wrong with my blue discus? He/she has over the past couple of days developed a big white lump on it's back and I have no idea what to do.
Does anyone have any advice?
I am almost certain that that is hole-in-the-head disease. It is very common on Discus and also common near the head(duh). It isn't always on the head, though. I would advise you to look at this: << http://www.aquaticcommunity.com/dise...einthehead.php >>
Thank you so much for your help. Will be changing the food straight away.
You're very welcome, glad I could help!
Oh man... That is one gorgeous fish! I hope he gets better soon!
