Please Any Advice For My Poorly Severum

[mrianna]

I have been treating my severum for six days with myaxin for columnaris, he still has a few cysts and today he is not eating and is hiding I am worried of what i should do next. None ofthe other fish in tank have been affected as yet it seems. any advice would be appreciated thankyou

Size of tank in gallons or litres.
How many fish and which type.
Water stats in ammonia, nitrite, nitrate and ph.

The lump does it look hard or soft like filled with puss.
Any redness to the lump.
What does it look like when the fish goes to the toilet.
Any red patches or red streaking on the body.

Does the fish have columnaris as in the uk you use pimafix with the myxazin.
