Dwarf Gourami Has A Sore/scales Missing On Side Of His Head

Dwarf gourami has a sore/scales missing on side of his head, probably from bashing it on net when moved.
Other wise perfectly normal
Just wondering how long it takes for scales to grow back & what i should do to treat/prevent any infection that may take hold while injurgy is there. Possibly become more of a lump since i 1st noticed it, so i thought it might be infected.

Tank size:200L
pH:7.8
ammonia:0
nitrite:0
nitrate:10
kH:
gH:
tank temp:26

Fish Symptoms (include full description including lesion, color, location, fish behavior):
Male Dwarf Gourami has gap in scales on head, I think caused by the net when i moved him into my new tank (set up for a month now & cycled). theres just a few scales missing, but the gap looks a little bit more like a spot/inflamed now. Its not red, Ive been looking through other posts & pictures & havent seen anything similar. Doesnt appear to be any fungus. Im thinking its either just healing up, or possiblly its got a bit infected & inflammed, so just want to make sure Im doing the rihgt thing before early on.
Otherwise he seems perfectly normal, eating fine.

Volume and Frequency of water changes: Changed about 10% water before started adding meds. Havent done many changes yet as only had fish in for 2 weeks & for 1st week was just 5 tetras in a very big tank!

Chemical Additives or Media in your tank: I removed the carbon from my filter & dosed with Azoo Magic Disease Treater. ive added the amount it says on pack yesterday & day before (says to add x amount /L every 24 huors for 1st 3 days)

Tank inhabitants: 5 neon tetras & 1 male & 1 female dwarf gourami

Recent additions to your tank (living or decoration): the gouramis have been in a week, although there were together in old tank for months

Exposure to chemicals:

Digital photo (include if possible): will post tonight

Not heard of azoo but I would treat with melafix if its just scales missing, probably a little infected but if its not red or inflammed then melafix or just good regular water changes.

Any signs of flicking and rubbing as sores and scales missing can be parasites.
Also I would look a gourami desease to rule it out.

OK, now Im home I think its got worse, now it looks red.
Ive taken photos, here they are.
Il keep checking the water perameters & use the AZOO magic disease treatment (http/www.aquaessentials.co.uk/inde...oducts_id=2039). It says on the bottle that its for fungus, bacteria & ectoparasites.
I dont know what else to do, are there better treatments out there? What is Melafix?
Really dont want this little one to get worse, I feel really guilty because Im sure it was me & the net that did the damage in the 1st place.
Hope you can help!
Many thanks

Did you read that link that I left.
Sores that are red and have a circling of white dead skin around the edges are ulcers.
Looks like a growth in the pic.

yes I have read your article, very interesting.
Im not sure what you are saying about sores & ulcers; which does he have & what does it mean for treatment/ survival chances?
He seems really fine otherwise, eating & swimming around as ususal.
What should I do with him??!

Can you issolate the sick fish.
I would try a bacterial med.
Melafix is only good on cuts and wounds and that it.
Uk anti internal bacteria med by interpet.
United states maracyn plus.

OK, I can sort of isolate the fish, i can put him back in my old taknk (30L) that has 2 guppys in it that I was about to move into the big tank. I suppose Il move them out 1st so hes on his own.
The meds Im using is Azoo magic disease treatment
http/www.aquaessentials.co.uk/index.php?...roducts_id=2040

its says it treats bacterial infections, but I wonder whether that incldes internal?
they mention "bacterial diseases such as Fin Rot, Ulcers, Infectious Dropsy and Ascites"

I will buy the interpet anti internal bacteria if it will do something different. How long after dosing with the current meds can I add the new one? Should I keep the carbon out of my filter?

Many thanks

Ok.
A broad spectrum med should treat gram positive and gram negative bacteria's.
I would carry on with the med if there no improvement get back to the board.
Good luck.
