check p 37. I reckon it looks like red spot disease.

or a couple of pages further in... could be columnaris which is a bacterial infection... same a for humans bacterial infections need antibiotics... and in aquaculture pathogenic infections such as what cause red spot disease require formalin to kill the pathogen. As with any fish health issue, salt will help by reducing the instance of fungal secondary infections.

First thought as well Monya.... and haemorraging lesions would indicate that posibility...

But the very definite "ulcer" pictured... is more likely Aeromonas salmonicida ...goldfish ulcer disease... "GUD"...

it looks terrible whatever it is. would a disease like this come from the hatchery Rupe? If so they might need a phone call and let them know.

Thanks Monya, I've had a read thru those sections, they do seem grim, don't they. I'm now of the opinion of removing the fish, ridding the system of the infection and starting over. Would love to know where the disease started. Also would love to hear opinions on how to rid the system of the disease. Am considering Rups salting at 6ppt and Condes at 2ppt for a ftn, hoping to keep the veggies and gravel for "Mattquaponics Take 2".

Where did you get the fish from Matt? You should contact them especially if you never had any other fish in your system

these are my first fish. they were purchased from a fishy dealer north sunshine coast. I'll be contacting them first thing next week. is there any other way they might have caught this disease?? Water always from a tank? 2 different gravel supplies??

Can anyone recommend how to sterilise this system now?

Chlorine. I would use the rates recommended for Mycobacteria on page 46 as without laboratory testing you dont know what you are dealing with here.
