Help Needed From Experienced Aquarists

[Morphious]

Hi guys and girls, apologies fir this being my first post however I have recently took up the hobby of keeping tropical fish. Done it as a very young boy but as always, parents done everything for me lol. I have started with a few hardy common fish, danios, platy's and guppy's. One of my platy's has a white fungus / ulcer on its back just before the dorsal fin. I have purchased interpet no8 thinking it was fungis and applied one dose on Tuesday afternoon although it appears to be getting a little worse. Can any of you confirm that it is fungus and the best course of treatment.

Looks like columnaris.
Is the area fluffy like cotton wool.

Myxazin by waterlife and pimafix.

Do a water change and run some black carbon for aday.

Add the myxazin by waterlife and pimafix.

Looks like columnaris. I'm impressed he's still alive! In the future, bear in mind that it is often hard to distinguish columnaris from fungus but since columnaris is far more common and spreads eons faster, it is safest to treat for columnaris first. That way, your fish will still be alive come plan B if the columnaris treatment doesn't work, ruling out columnaris. The difference is that true fungus is... well, a true fungus, while columnaris (sometimes called body fungus) is actually a bacteria. If you can find Maracyn that will work but if you are in the UK you'll have to wait for a UK member's advice.

EDIT: Whoops-- there you have it! I was typing as wilder posted lol.

You can also try Melafix. It works wonders and has saved many of my fish in the past.

I wouldn't bother with the melafix. If its a bad strain of columnaris it won't work.
Melafix is only good really on cuts and wounds. its overated.
